I bought it on sale for 43 euros and I am completely satisfied at this price. I wanted and got something basic and reliable at a reasonable price. The only thing that bothers me is that I have no idea what the dial says when I'm outside in the sun. Otherwise, it's very comfortable on the wrist, has a huge battery life, simple setup, easy app, and simple functions. I also bought it as a gift for my friend at the same price and she is very satisfied as well. I set it to remind me every hour to take some steps so that I'm not stuck at my desk, and I have already noticed a difference in my well-being. I recommend it

Compared to the Inspire HR that broke on me, it is much improved in terms of functionality and battery charging. It also has a battery life of 2 weeks.

First of all, for those who don't know, there are "smartwatches" and "trackers". The inspire 2 belongs to the second category.
It doesn't have an oxygen saturation meter, a thermometer, contacts for electrocardiogram, built-in GPS, microphone, and speaker. It has basic notifications, but I haven't activated them. Anyone interested in these features should get a smartwatch.

Its screen is black and white, not OLED, and occupies only a small central part of the "black" surface.
Its main functions are to measure heart rate and movement/activity. Based on these characteristics, it measures "sleep stages" through an algorithm system that is not available to the public.
You need to create an account on Fitbit, which has been owned by Google since 2021, with all that it entails. Also, not all the data it calculates is available, so a premium subscription is required. It offers 1 year for free, but you need to input a credit card and "cancel" it if you don't want to be charged after the year.

It is relatively expensive for what it offers. With less than half the price, you can get another brand with more capabilities. I chose it because it has the reputation of being accurate in its few measurements, and that's what interested me.
Its battery actually lasts for 10 days. The screen is not visible under the Greek sun, even if you activate the dimming function. The strap must be one of the most tolerable on the wrist, but it gives the impression that it retains moisture for a while after washing/drying your hands.

It doesn't have apps and has very few skins that don't make sense on a black and white screen anyway.
Everything is done through the Fitbit app, which is not the easiest to use. It also annoys you with the fact that it has many features that require a premium subscription, and the app keeps reminding you of that.
The current app works on my Android 11 phone, but previous versions didn't open (and for other users) so my advice is to try the app before purchasing it.
