I was allowed to test this product and I am very happy with it! My old versa needs to be replaced. I've been a Fitbit fan for years. Not only because it helps me to get my steps, also because I like the different straps with an outfit. I am surprised! There are new functions, including a heart movie. I really think that's an added value! The design is also better, the edges give a luxurious look. I am also very happy that the button on the side is no longer hidden, that did not work well. This is great!

Looks nice and battery lasts a long time, especially compared to other smart/health watches. But in terms of operation / display (at the moment, not yet?) optimal. New model, so hopefully it still concerns teething problems that will be solved with updates. However, at the moment I am unfortunately annoyed by, among other things, texts that are poorly displayed, but half synchronize (such as sleep not visible with reference to 'no data' on the watch, but in the app), temporarily not wearing what is sometimes registered as sleep, etc. Not being able to (compare) heart rate monitor with another device. I use the Fitbit Sense 2 in combination with. an iPhone, which should work fine, yet I often have to sync manually instead of automatically. It is also a pity that Spotify and Google assistant have been removed from the Sense, these apps and others can no longer be installed on the Sense 2. Mine is unfortunately going back.

This watch has a small watch case. We recommend these if you have a maximum wrist circumference of 15cm. Measure your wrist circumference 2 fingers above your wrist joint, just above the protruding part. Is your wrist circumference larger? This watch may not be the best for you. Read which watch case size we do recommend.
