I decided to try out this watch instead of buying a new Fitbit or even instead of signing up for the new yearly Fitbit subscription because it seemed like it was not only on par but possibly better than a Fitbit but also I liked how the software didn't have an annual subscription cost.As someone who exclusively used Fitbit before I am amazed with this watch. It not only works better, syncs faster, and lasts longer than my Fitbit I like the way it looks better too. I really like the software as well, it does all of the same things and I think more than my Fitbit software even when I paid for it.I am a disabled cancer survivor so I do need to make sure I keep an eye on my steps, and things like my heart rate throughout the day. I also really appreciate the sleep tracker because a lot of my health issues also make me have terrible insomnia and knowing when Ive actually slept and when I need to maybe rest more is very helpful. I also really like that this one has a built-in gps. All of my other smart watches didn't have built-in GPS but even when I had my phone along for the ride the GPS never worked well. Some of them it never worked at all. Using this one I take my dog for a walk and just turn my watch on to record my trip and everything works perfectly, every time even when I don't have my phone. And the biggest surprise was the battery life. I have had this watch last me a week or more. I'm not even sure how it does that, as my old Fitbit had to be charged every 2 days. And even when I had a Fitbit without the screen it still had to be charged more often than this watch.It will be going on about 5 months that I've had this now, and it still looks brand new as well. I also really appreciate that the bands are much more affordable than trying to buy replacement Fitbit bands. Overall I am not only happy I found this watch but I am a converted loyal customer to this brand. If I need to replace this, which I'm sure at some point I will, it will definitely be a watch from this same brand.
