This sealer works great and has saved me money and food. It is easy to use and clean ups easily. Great for leftovers and if like me when you buy in bulk you know it will stay fresh.

With the pandemic and concerns about being able to get supplies, I started buying some items in bulk and wanted to be able to store them so they would retain freshness, especially meats that can easily get freezer burn. I read a lot of reviews on sealers and was having a hard time deciding which to get. I was not sure if I needed to get a large one for power, but I did not want something really big that I would use infrequently since then it would be taking up space on my counter or sitting in storage where I would not want to go through the hassle of getting it out to seal a small number of items. I was also wary of what I heard was a high volume of fake or purchased reviews by sellers.

I took the dive on the Koios last May and have been really happy with it. It does not have a big footprint or take up space, so I can store it when not in use and easily get it out even for one or two quick seals, and it works great!

I have used it for dry items (rice, nuts, popcorn), for meats, and for wet items (we prep and freeze a year's worth of hatch chilis every year) - anything I want to keep fresh longer. The process works smoothly and quickly. I buy meat in larger, less expensive quantities and then vacuum seal and freeze smaller sizes. It is easy to take out a bag of frozen chicken, for example, throw the bag as is into water with a sous vides while I go back to work, and it comes out ready to eat with no further effort! If I want to prepare it in a different way, I take it out the night before and it defrosts in the fridge without dripping all over the shelf. And the best thing is that meat not only stays high quality in the freezer, it no longer gets freezer burn. Everything I have sealed has stayed sealed with no air leakage.

I waited to write a review until enough time had passed to really give it a workout and I have no reservations in recommending it.

Good value sealer, but annoying request for 5-star review

Reviewed in the United States on October 9, 2018

After receiving repeating emails from the seller offering me a free 4k action camera in exchange for a 5-star review, I thought I'd write a 4-star review and make readers aware that all 5-star reviews for this product are suspect. I'm sure most are honest, but all are suspect due to the actions of the seller.

Nevertheless, here's my experience with and review of the KOIOS VS2233:

This is a very decent vacuum sealer, especially for the price. I have been using it almost daily since I purchased it - mostly for sous vide cooking, but also for packaging food for freezer storage. I typically use it with FoodSaver brand bag rolls (I have a bunch), but have used it with "heavy-duty" bag rolls, too.

There are features I would have preferred to see, but they're reserved for the higher-priced KOIOS model. I'd have liked to see a removable vacuum tray to make cleaning easier. I'd have also liked an "inching" or manual vacuum function, but that can be roughly simulated by starting and stopping the Vacuum&Seal operation. None of this is a surprise and didn't affect my rating; I knew these features were not on this model.

BTW, I have not used it to seal "chip" bags. Honestly, binder clips work very well for that task and are readily available from the office. ;)

I do have a few specific gripes about the VS2233:

The Vacuum&Seal (auto seal) function continues sucking on a vacuum long after all air has been removed. Eventually it's satisfied and seals the bag. I don't know if the lengthy suck session indicates a poorly adjusted sensor or if it just cuts off after a fixed time, but it's annoying. When it does this, I usually jut press the manual Seal button to stop the vacuum and immediately seal the bag.

Another minor complaint I have is the excessive grip strength needed to latch the lid. I find I often have to grip the front corners and squeeze fairly hard to get both sides to latch. And while the release is very easy with the two side buttons, I worry about eventual wear on the latches.

Things I like:
In general, it works well. I found it to be a good value - worth the money.

It wasn't broken on arrival; it was brand new and wasn't soiled or used - a plus. These conditions are expected but are not always a given, even when "Fulfilled by Amazon." [I once bought a "new" rice cooker here, FBA, that arrived filthy and with cooked rice still in the bowl.]

In particular, I liked:
The heat-sealer part worked very well. It powered through a bit of water on the bag without problems, even on Dry food mode. It also sealed the slightly thicker "heavy-duty" bags that two of my previous vacuum sealers had real problems with. Examination of the seals made by the VS2233 showed a wide, uniform seal across the entire length of the bag.

I first thought the little cutter included with and stored in a slot in the sealer was a bit of a gimmick. Just use scissors to cut the bags, right? But I found the cutter to be convenient and practical. I also get straighter and cleaner cuts with it than with scissors for some reason.

The vacuum motor is certainly strong enough (and loud enough) to draw a good vacuum and it does a fine job. Other sealers I've owned would cut off the motor automatically before I was truly satisfied. This one is more satisfying - possibly related to that vacuum sensor adjustment I complained about earlier.

Overall, I really like this vacuum sealer. I've gone through a couple of other "value" sealers that didn't work very well, or for very long. I'm glad I found this one - it works as I would expect and it appears sturdy enough to last. I'll know for sure in a few more months.

It will do the job.

I needed something that wasn't expensive but could keep my food from going bad. I like to buy in bulk since the cost is cheaper than constantly buying little by little at the market but we don't go through the food fast enough. I spent 4 hours packaging all the food into bags and really test this machine out. I used it on large meats, fruit, veggies, bread and even herbs.

Pros:
1. Its not the cheapest nor is it the most expensive. It was between this one and Amazon's top choice for one that was only $20 which had decent reviews.
2. Its not really bulky and can fit in a drawer IF you dont have anything else in it.
3. Works Fast
4. Can do multiple items back to back with out waiting in between.

Cons:
1. It's not as slim as the cheaper models for storage.
2. There isn't a option to hold the "suction" for as long as YOU want, its pretty much timed for about 30 sec-1 min and it automatically switches to "Seal" to close the bag. I used this on fruit, and the first few bags crushed the fruit completely as well as my bagels.
3. If you're using the storage rolls to make your own "bags" you really have to guess to what is too much room and too little "excess" at the ends because the machine will just continue to pull the air out forever if you dont stop it.

** After 1 week of all my items being stored and finally opening some of them***

->The fruit I sealed and placed in the freezer tasted fine after using them for a frozen smoothie, however I wouldn't recommend doing this and then thawing it to eat like "fresh fruit". The juices from the fruit were squeezed out from the machine which made a syrup like bubble around the fruit.
->My herbs were well preserved. Separate them into sections for best results instead of trying to store a bunch at once.
->My veggies had a slight watery residue after unsealing the package. I'm not sure if it was because they were not dried after washing them completely or if it was because the machine didnt completely pull ALL the air from the bag and left room for condensation to develop.
-> So far no frost has developed on the meat I've stored.
-> The bagels I saved were crushed from the air being pulled out, but if you stop the suction mid way and press the "seal" button before it gets crushed it will work just fine.

I would recommend the "TWO ROLLS" of plastic that Amazon recommends to make your own bags. Its less expensive that pre package bags, and you can make any size you want. I've barely used half a roll when I packaged, 3 Large containers of fruit, 5 different herbs, 5 different veggies, 13 bagels, 2 racks of ribs, 4 different packages of chicken.

This would be a good buy if you are looking for something that does the job, but isn't professional grade vacuum sealer. It's not the cheapest, but its not crazy expensive. This was still worth the buy. There was so many to choose from online, but after everything this was still my #1 choice.

This machine sucks

The air out of the bag to keep food fresher longer. I buy my meat in bulk then break them down into smaller packages for freezing. This machine works surprisingly well, so I’m happy with it. Pretty easy to use and gets a good suck and seal every time! Can’t go wrong with a consistent suck.

Works as intended.

Was sceptical of some of the reviews when I saw they were offering free products in exchange for positive reviews. I intentionally did not submit a review until I had a chance to use it a few times with a variety of stuff and did not submit for any free products. I've done 10 lbs. of coffee beans, ~30lbs. of ground beef, bunch of veggies, some small med kits for camping and a few other small things. Also used the included vac bags and some other stuff that comes on a roll. Both seem to work equally well.
I haven't had a single problem with the machine. A couple user errors like getting a coffee bean between the top and bottom so it wouldn't hold a vacuum. However the machine just won't seal until it can hold the vacuum. That's a nice feature. Vacuum is very strong. My bags of coffee beans are hard as a rock. Everything I've tried has worked very well.
I've read a few reviews stating it pulls liquids into the machine. Think about this for a moment folks. You are pulling a strong vaccine on a liquid. Of course it will pull a liquid into the machine. Have you never used a straw? You can't exactly vacuum seal a soup in a bag and expect it to not pull liquid into the machine. Face meet palm.
I have done some fairly moist veggies and fruits and had no issues. So I can only assume people are trying to vacuum seal liquids. My hope in society is dwindling. If you want to do liquids, they make vacuum containers exactly for that purpose. I haven't tried that yet but might in the future.
Use it as intended and it has worked well so far. Can't really comment on longevity as I've only had it a short while. At this point I feel it's a very good machine for the price.

Don't waste your money

Reviewed in the United States on July 7, 2019

I was looking forward to using this for garden vegetables that I normally put in ziploc bags. I just wasted my money!! First, it will NOT vacuum and seal. That button only vacuums, it will NOT seal anything. Not even an empty bag!! You have to let it vacuum and then hit the seal button and wait a few seconds and hold your breath that it sealed. The instructions are just awful. They do not explain anything other than place the bag on the front, close and lock the lid, hit vacuum and seal. I did that about 7 times to no avail, then I went to empty bags and tried, still would not seal!! So, one last time I tried vacuum and seal and then hit the "seal" button on the left and it made a seal. The instructions do not tell you that!! That was with sliced up fresh yellow squash. Got that done. However, when trying to seal my grated zucchini it will NOT make a seal, just pulls the little bit of liquid up into the rim and will not make a seal. So, if you are willing to make lots of extra effort to seal something that is not totally DRY (the moist button does not help) then I'd suggest you save your money. Yes, I can send it back, they have Amazon return, but that will cost me whatever they decide to deduct from your refund and I've found that is usually a lot, so normally I don't even bother to send stuff back because of that reason. I'll keep it to just do dry things and realize it won't always work as it should. Another thing is that they put some extra things in the box. One I figured out is a seal. Then there's some sort of hose in there. NOTHING in the paperwork explains what these are for or how to install. Guess you have to already know. I suggest looking somewhere else for a sealer.

Good product for the money

Reviewed in the United States on October 2, 2019

This is a good machine for the price. The instructions are not clear at all & this was my first food seal system so I wasn't familiar. After some practice, easy enough to figure out but reading thru instructions 1st time - not clear. I bought this to vacuum seal a lot of fresh roasted green chile that we do every year. I put the suction on moist and it worked fine for 3-4 times but then no suction. Had to wait 5 minutes & then it would do maybe 2 more & then not. Wait 5 minutes and then it would do 2 bags and stop again. I had to do about 40 bags so that was probably more than it was designed for - not sure. When it suctioned right - it did a good job. I'm sure if I bought one for a lot more money (more than $100) then they probably would do more at a time. For this price, I feel it was a good deal and did the job. Just can't do a lot of moist vacuum sealing one right after the other but if you only have a few things at a time - works fine. Otherwise, just plan on waiting up to 5 minutes between vacuum seals.

I would recommend - good for the price - compact as well.
