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.

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

I've had this for less than 2 weeks and on 3rd time charging it from flat battery, usually the 3-4 similar watches I've had previously would last at least a week before needing charged and I'd get a warning vibration that the battery is low but with this one I just go to check the time and find it not working, around 3-4 days between charging,. Another issue to note, cannot put your actual stride length in settings anywhere to get accurate step count, I will say the graph of steps does seem to match activity but I think my actual steps should be showing around 25% lower from years of experience with pedometers/more accurate step counters. Other the watch seems fine but probably won't last too long but I don't mind replacing once a year on average with these style, cheap smart watches, I buy them as I have various straps that fit most of this usb type watches. My last two smart watches I broke off at usb on one and other I lost.. Hence not fussy about £8-10 replacements when required...

Nightmare to try and charge. Doesn't work. Waste of time

I wanted to try this out before investing in a higher quality product.First impression is that is it very cheaply made but for £10.99 I wasn’t expecting a Fitbit, on the flip side it charged incredibly quick and seems so be doing what I bought it for.The app is great with loads of different displays.I am hoping that the step count is fairly accurate as that’s what I bought it for.The only negative on first impression is there seems to be a few damaged pixels on the screen that’s looks like a green blob, however this doesn’t effect the use.Overall, for what you’re paying its worth it.

I bought this for my grandma who’s in her 60s not very good with technology. It was so easy to set up, she can see her steps heart rate etc. the other features such as phone connection as great for her as she misses phone calls a lot. Great quality for price

It really doesn’t work very well, got it for my little boy but the steps don’t count properly. Walked down one flight of stairs and it counting 528 steps! Don’t waste your money

It didn't charge at all and difficult to link with the phone
