A great purchase, value for money
First time owing and Smart watch.
Did a lot of reading and YouTube beforehand.
Will consider this as an fitness tracker , rather than a smart watch.
Was a little disappointed that this didn't have NFC and blood pressure sensor, however you get what you pay for.
It's not a high spec watch, and I understand if you want all that you would need to pay for a higher spec version or go with a Garmin watch or sth.
The strap isn't that easy to put on either. But the strap does feel comfortable.
However , having said all that, I think this watch is great , resolution is really good.
I bought it because for this price it's got GPS as well, ...view more
Good smartwatch
Really like the looks and design. The only think minus for me is there is no way to view next song list/ chapter of audiobook. Battery last forever.
Better value than proper smart watches
Battery life seems good.
Redmi watch 4
Very nice watch! Great use experience with great looks.
Great value
This is a solid product, does everything fairly well. Looses points for me because the calorie counter is wildly inaccurate.
ANNABELLE
this watch is the best and best teach.
Great value!
Good clear bright screen with plenty of watch face options. Battery lasts way longer than expected.
Strap easy to do up - especially after you read the instructions!
A great watch at this price
Great price and excellent watch
Unreliable Heart Rate Counter
The heart rate counter is inaccurate. It gives you a 150-per-minute reading while it should be under 70.
A Great Watch with Great Price
Excellent product features in this competitive price by PBTech. Watch is really elegant with tons of features and super long battery life. Watch is quite handy in situations where phone is away and you need to answer the call or make a call directly on the watch.

Amazing watch!
This watch exceeds my expectations. It has many functions including being able to make phone calls from the watch, as well as receive them on the watch. It has a Find my Phone function as well as a Phone Camera control. I am still discovering things it does (I bought the phone yesterday). It has a lovely big clear screen with long battery life. I highly recommend it!
Awesome sport watch
Awesome battery life with modern look, sport feature with loads of training informations. Bought with discount price, very happy with the purchase!
