Pros:--This set has 3 sizes of rollers, which makes it very versatile, an excellent adjunct to another set - and also a good starter set for those new to hot rollers.--The rollers are hollow and get hot by being placed on heated metal rods which stick up from the base. It's simple and straightforward.(Many roller sets need to be aligned and pushed in place so the elements can make their necessary contacts. If you don't get them in correctly, the rollers don't get hot - not an issue with this set.)--These rollers get hotter as they sit on the base. Once your find your groove, know how hot you need your rollers to be, you can use this to your advantage by unplugging the unit when they reach your desired temp. (Though you'll have to do this by time/feel - there are no indicators on the rollers. If you leave them too long, they may feel too hot.)--I like that these have a hard plastic finish, (not flocked or velvety), and that they have little spiky nodes. The barrels are continuous, (no wedge cut-outs) and very light-weight.--The set comes with pins to secure them in place. Once you get the hang of the pins, they're easy to use and require less storage space than clips. (This is a good thing for me. Some folks prefer the clips.) The only bad thing about these pins is that it's easy to get them mixed up - while they are marked in different colors to indicate the size roller for which they are intended, those colors aren't distinct enough.(It's really frustrating to grab the wrong pin when you've got that roller exactly in place.) Just be sure to put the pins in size-piles before you start rolling...--Everything stores away neatly in the heating case.--You can buy extra clips & rollers directly from Conair - (last pic is from booklet with ordering info)Cons:--There is no on/off switch. You must unplug the base in order to turn off the curlers. (There is, however, an indicator light, which is good.)--Melting the curlers is a real risk, especially if you forget to unplug the base. The posts do get very hot and while they do an awesome job of heating the curlers, it seems that extended contact to the elements might not be a good thing.(I've left mine fully heated for about 45 minutes with no melting problems - but the curlers were uncomfortable to handle when on the base for that long.)--This set doesn't have "ion technology" or ceramic cores... or whatever the latest & greatest is in hot rollers... If this is important to you, look elsewhere. (I'm not troubled by that - I don't use rollers every day and I take care to use a thermal protectant spray on my hair when I do use them. My hair is soft, healthy and not impacted by the absence of the technology.)--If you wish to use all of one size, you probably won't have enough curlers in this set. I like to use the larger ones on the top of my head and medium or small on the sides, depending on how tight I want the curls. (But I always want the top to be a little looser...) That being stated, at this price point, it's a great way to try a few sizes and see what works for you.Overall:This is a terrific product. As with any item that generates heat, care must be taken to ensure that it is turned off when not in use. It's a no-frills curler set and it does it's job well.The curlers don't have individual components inside, which makes them reliable and lightweight - they're hot when I need them to be and a full head of curlers doesn't weigh as much it does when using the higher-tech ones.I use these in conjunction with the Calista Tools Ion Hot Rollers Long Style Set 12 Base - (I really like those too!) Combining these two sets frees up the large rollers (in this set) for days that want a more "beachy" look. (The two sets compliment each other nicely.)
