I was in early backer of the powerwatch on indigogo. I quickly upgraded to the power watch X when it became available, in talking to their customer service when everything was said and done, They said I could expect apple health sinking and a variety of other software features. I purchased the watch over two years ago, I finally got it a little over 2 and a half months ago. There are minor issues with the watch itself that are related to the hardware, things like the poor quality light for the display. But other issues are software related, and I’ve been waiting months for those to be fixed. The watch does not connect to Apple health, often I have trouble getting it to connect to my phone. There are a total of three watch faces, not the half dozen I was expecting, and the software allows for virtually no customization beyond selecting a particular watch face. If they had followed through with the promises of the software, I would probably still be wearing mine instead of having it sit on the desk at home while I use an older Apple smart watch.

Poor software quality

Well, I’ve been very displeased so far with the performance of the PowerWatch X. I had gotten it for Christmas and right away was having connection issues with my iPhone Xs. I contacted support, sent in the watch as it was not giving me any notifications, or syncing. Two months later I have a brand new one as the one I received for Christmas was determined to be defective, and I still don’t get notifications on it, but it does at least sync with my phone. The software, if that is indeed the issue, NEEDS SOME MAJOR WORK! I’ve not tried using it for a run yet, but I would think that would be pointless to try at this point as there is no syncing with any of my run apps. The Apple Watch is much better.

Waste of money

As another reviewer here, I am an early backer on indigogo. I waited almost two years to get the PowerWatch X. Besides all those things mentioned by the others reviewer (poor light, can’t tell the time bc it is too dark, not enough faces-can’t tell the date). The software issues are the biggest problem. I don’t get notifications as it was advertised. The watch stops syncing after 7-10 days. So I have to unpair and pair the phone with the app twice a month or more often. The company said the issue was with my phone, but I tried it with a new phone for 3 weeks (with somebody’s else new phone) and the problem persisted. When I asked for a refund—within 2 months—they ignored my requests until finally they said “Your order had already passed the refund period of ours.”
The idea was right, but this company doesn’t care about making things right to their customers that supported them from the start. I use my regular Ironman watch than this watch.
