Customers are mixed about the battery life of the wearable computer.

153 customers mention56 positive97 negative

Customers are mixed about the performance of the wearable computer. Some mention that it works perfectly, is easy to use, and understand, and pairs beautifully with their Android phone. However, others say that it didn't perform well, is seriously odd in how it functions, and is inaccurate.

97 customers mention62 positive35 negative

Customers are mixed about the ease of use of the wearable computer. Some mention that phones calls, etc, are all easy to use and set up. However, others say that the device UI/UX is clumsy and difficult to navigate, it takes a few minutes to recognize workouts, and it needs better instructions for set up, and the steps are not accurate.

"...The accompanying app is another highlight. It's user-friendly and intuitive, making it easy to navigate through my health data and set fitness goals...." Read more

"...for that kind of money, you wouldn't expect a strap that is so difficult to fasten (peg in a hole type) that my wife returned her watch...." Read more

"The watch itself is fine. A bit pricey, compared to many other watches with similar functionality, but otherwise acceptable...." Read more

Customers are dissatisfied with the app of the wearable computer. They mention that it has zero third-party app support, the apps available are greatly reduced, and none of the third- party apps work with the Versa 4 or sense 2.

Its a Fitbit, it works for a year or two and the band sucks
4 Stars
Its a Fitbit, it works for a year or two and the band sucks
I have used Fitbits for about ten years. The problem I have with all Fitbits are that the bands are trash and will break out your wrist. The charging interface always sucks and they die after a year or two. I ordered new cloth bands for my Sense one and they fit the two, so when my Sense died one I was able to put one of them on the new tracker. picture with cloth band. I am a potter and the little charging pads on the back get clogged with clay. Any mud will do this and you have to take a tooth pick and dig it out before you can charge it. The charging cord it comes with will stop working in a month or so, all of the after market chargers seem to work fine.
Thank you for your feedback
