The numbers are easy to read. I find the balance quite sober but classy and especially mixed. It is a beautiful object that looks pretty solid and reliable. I do not trust myself totally to these indications (muscle percentage, water, grease, ...) but it gives a small indication and monitoring especially when we do sports sessions on the medium term! In short, it is a good product, without actually defects. I did not actually use the Bluetooth function, but it is mandatory to download the application (in my case on the smartphone) to take advantage of all these indicators.
