Matrix Industries PowerWatch – Smartwatch, no charging needed, works with body heat, 200m 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 darker this 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.

The PowerWatchX is fantastic. I cannot believe that the watch requires no battery power at all, especially given all of the features that it has. It tracks calories, it tracks sleeps, and there appear to be notifications that it can also provide (though it would be helpful to understand more how these sync up with a mobile device). This watch has a larger face, but doesn't feel that way when wearing it. The silicone strap is SUPER comfortable to wear and it really does seem unbreakable. It also has some give to it which makes it more comfortable to wear. Moreover, this model comes with a thermal charging pad in the event that it runs out of power (because you haven't worn it for a while and haven't been providing it body heat!). One area of improvement would be the app and the syncing between watch and mobile device. It's not clear to me whether this happens automatically, and if not, there should be some way of doing this similar to other smart watches out there. All in all, though, a solid product and great buy.

Le faltaria un poco de LUZ adicional para la lectura nocturna Hasta ahora ha funcionado bastante bien , pero lleva unas semanas que no carga cuando está puesto o no lo suficiente y al cabo de unos días se desconecta . Tampoco sincroniza los datos de calorías . Un fiasco !!! Y eso que es bonito . No lo recomiendo

Devo modificare il mio parere espresso ad Aprile...E' la seconda volta che succede....all'improvviso lo smartwatch si spegne completamente e per farlo ripartire devo usare il suo caricatore termico. La prima volta ho dato la colpa dello spegnimento alla permanenza in connessione con il telefono via bluetooth. La seconda non ha motivo avendo spento la funzione sul telefono ! Ora il problema potrebbe essere che usando una tastiera bluetooth connessa al PC ...lo smartwatch di suo....cerchi di connettersi continuamente non con il telefono... ma con il PC ! Così non va bene....attendo una risposta dall'assistenza....ma sono intenzionato a renderlo mio malgrado.

I love well engineered things, and this takes the cake! It never needs charging!

Horrible, malo, temible estoy arrepentido de haberlo comprado ni siquiera se puede sincronizar
