Difficult connection - configuration. Poor quality (the strap broke on the second day). Small and with a very small battery (for a day)

The band is obviously one of the most low-end in the market, but for the money it costs, it deserves its stars.

Comfort
Moderate quality strap
Moderate number of functions
Relative accuracy in measurements
Quality-price ratio
Battery autonomy

It could have better battery saving and the glass scratches easily... after the warranty expired, it broke.

Good watch/step counter. It's worth its money (8.30€) ordered from Ali Express. Okay! The strap is so-so, it fits well on the hand but lacks in quality. The mobile application recommended by the manufacturer is terrible. It needs a lot of work. Okay, it's something simple and economical, otherwise go for the Mi Band 2 now that the price has dropped (15€).

One of the worst products in its category in terms of price and quality ratio. Unless the product had a factory issue. I hope the store where I ordered it will make the exchange for me.

I use it mostly for cycling. It measures heart rate and steps very well. The battery lasts for many days. It is a very good watch

I do not recommend it. It is a blatant copy of the Xiaomi Mi Band 2, which is already at a good price ($30).
If you want an activity tracker or any other technology product, DO NOT choose OEM!

Very good active watch! It measures very well for... a watch!
The blood pressure and heart rate measurements are very close to reality with simultaneous measurements with a wrist blood pressure monitor and an oximeter for verification!
It accurately shows the distance traveled. I haven't measured steps!
A very good choice for its price!
Only time will tell if it will withstand as well!
