## Customer Reviews

### ⭐ woeful; useless
*by R***S on 9 September 2024*

I tried to find a good point; time is ok and can have 12and 24h. Date is not the proper way round; sitting in a chair for 4 hours gives 10000 steps so useless; heart rate very innacurate; charging is hit and miss; and it says battery full but as soon as it goes down to 3/4 you have about 10 mins left so no good if you are outside and need the time as it's flat soon enough. Did try the time with no colour and no pictures which made it last a day or more but with so few features working or acceptable I sent it back after 25 days as it may after all give up just after Amazon return window given it's such poor quality; should not be sold.

### ⭐⭐⭐⭐⭐ So easy to use
*by W***R on 13 August 2023*

Bought another type previously and was confounded by all the 'download this and upload that and the subtract the number you first thought of'. This is a doddle to get running and working. GREAT

### ⭐⭐⭐ Doesnt last long
*by K***N on 28 July 2023*

Have to charge it every day
