First things first, I got the Sense for the promo price of $278 and wasn't going to buy it at the original price. When it went on sale, I thought it'd now be worth it but that is not the case at all. I don't even think it's worth $200. I will be returning it for many reasons.1. Phone DependencyIt's interesting that a $330 watch that has its own independent wifi capability as well as its own independent GPS still relies so much on being paired to a mobile phone. I didn't think this was the case before buying it but I learned very quickly and frustratingly that a few features are useless without phone connectivity (active pairing).--Information syncing: with its own wifi capability, technically a smartwatch shouldn't have to be paired to your phone via Bluetooth just to receive information and stats updates.A smart scale with WiFi for example no longer needs to be actively paired to your phone via Bluetooth to update your stats, you just get on the scale, get off and the data gets sent off. The phone doesn't need to be directly tethered to get an update of that info and as long as the scale has wifi, you should never need bluetooth. That's what a Fitbit -should- be like, but it absolutely is not and is completely dependent on bluetooth to send stats to your Fitbit app.-- Spotify: it neither stores music (downloadable playlists) nor accesses streaming music through the watch itself. It's merely a controller for the Spotify app on your phone. This kind of negates the point of independent GPS because... cool you can use the GPS for a run without your phone but then.... you still need your phone for music.--Google Assistant: is NOT built-in! Not in the way that would usually mean. Google Assistant piggybacks or hooks into the Google Assistant on your Android phone. It's not really an assistant app as much as it is a "relay." This means it doesn't work if the watch loses connection with your phone. Which, guess what my second big issue is:2. It loses connections a LOTRight out of the box, connectivity was a massive headache. This was the most frustrating piece of tech to set up and it probably shouldn't be that way for $300+. The way to set it up is to use the phone app to connect the watch to wifi or Bluetooth so that it can do all of its updates and syncing. Now, if you don't have wifi access, you can just pair the Sense via Bluetooth and set it up that way, however, it will take **hours** as the updates are probably massive.I know this because the Fitbit app could not find any wifi networks whatsoever during setup and after trying to add my home network manually and failing over and over, I opted for bluetooth setup instead. I left it for half an hour, came back, and it wasn't even a fourth of the way through on it's little progress bar.I decided I couldn't wait and wanted to attempt wifi setup again and after a few more tries it finally took. The update indeed went much much faster, but that wasn't the end of the connectivity issues.The Sense also just loses bluetooth connectivity a LOT throughout the day. And you'll find this out when you try to open an app that requires your phone to be actively paired (see my photos). Instructions say to turn the Bluetooth on your phone off and back on or restart the watch if you're still having connection issues and I cannot. Why should anyone have to be constantly restarting their Bluetooth or smartwatch for a $300+ premium device??Combined with the phone dependency of some apps, it's almost like you have to have your phone in hand any time you want to use the watch and this is NOT a premium experience for a watch that claims to be their newest and most advanced!3. The Fitbit app is complete rubbishI cannot fathom wanting to spend extra money on a subscription to Fitbit Premium, not just because we already paid $300 but also because even if the information and tracking was worth it, the app is so wonky that the extra info wouldn't be of much use.By wonky I mean that sometimes things don't register. I'll log water and it just won't show that I did it. I've tried again and again to log food by scanning barcodes and it just can't detect a single barcode. Meanwhile MyFitnessPal on the same phone can detect them perfectly. Trying to select watch faces for some reason caused the app to get stuck on me a few times and then lastly of course there's the lack of wifi detection. It wasn't just during setup, even if I wanted to switch the Sense to a new wifi network, the app still couldn't pull up any networks around me. Meanwhile my phone's OS will pick up about 15 networks around me instantly.On top of the app not being able to read wifi networks, it seems really cluttered to me and just not well organized. In some cases, I can see Sense data (like reports) but can't see what the data means. I can get a score of something, but can't see why my score is this and what the insight is as to how it pertains to my health. Like... cool, they boast all this data but it means nothing if we don't know what to do with it.4. UI / UX just isn't thereFor a $330 smartwatch, the User Interface is dismally basic and not as robust as I was expecting. The additional watch faces you can download aren't great and the user-made ones are truly horrible. The watch face doesn't wake up on double-tap every time, sometimes I have to try 3-4 times. I just was expecting more for something that cost more than my phone did.All in all I have had the worst buyers remorse I've ever experienced with this watch because for the things it does alright or well, it just isn't worth the money.
