MATRIX INDUSTRIES PowerWatch – Smartwatch, no charging needed, works with body heat, 50m water resistant, PowerWatch App, customizable - Black

Edit: Three months in (I'd opted to pay over 6 months, so i'm still paying for it) - woke up one morning and the watch had died, I had not got it wet, knocked it or damaged it in any way.I would advise anybody to avoid this watch, I had already regretted buying it after the first day of using it, even more so now. Dropped from 2 stars to 1, would give 0 if I could.This watch looks and feels great, and the (although limited) user interface feels great, and it charges itself through your body heat.However, the features that it does lack were ones that were present on my £15 smart band that it is replacing: heartrate monitor, GPS, Google Fit sync: for a fitness watch to not have this ability at the pricepoint it's at is a bit disappointing.

Bad:Overexcited step counter and sleep tracker, front glass scratches really easy. After just one month of ware the front has 3 scratches on it that are relay visible and ruin the watch.Good: Super light, water resistance good, no charging required, short and easy settings.Overall: just like a solar watch, limited features but no charging. I will defiantly not go fort the next model because of the screen that scratches easily

A watch powered by the wearer being alive, brilliant. Though I wouldn't say it's a 'smart' watch, more like a hybrid smartwatch.Just enough of a notification, to let you know something has happened.A pity that there isn't a wider choice of screens, but the ones there are, do the job.

Best gift for my husband

Watch looks nice but that’s were it ends , it constantly looses connection with the app , the display isn’t very clear as not back lit - only when button pressed does it light up, features very basic and to top it off stopped working altogether after 4 months .Short lived gadget which is only fit for the bin .

Would give this zero stars if possible.I had such high hopes for this product I was willing to forgive all the minor flaws that were present from day 1, lack of smartwatch functionality, poor quality display, poor back lighting etc. 4 months in and watch will no longer pair with the app, which means it not only will not collect fitness data, it won't even tell the time.Very heavy ugly expensive bracelet.

The picture that use are showing is incorrect the LED picture is a lot darkerthis was one of the reasons I bought the watch as I am registered blind.

A nice idea but utterly unreliable. You will waste hours of your life trying to get it to pair with useless app, then if you manage to actually get it to pair at some point the watch will just stop working and the LCD will go blank at which point you'll have to stick it on the supplied hot plate, then start the whole pairing nightmare again! Oh and the magnet on the metal strap is glued with a tiny, tiny dab of glue which means it'll fall out meaning the strap like the watch will be useless. Don't waste your money go buy a proper watch.
