The DT NO.1 DT99 smart watch is another Xiaomi Amazfit GTR inspired watch and maybe a little bit nicer (with metal strap). However, the price is only $40.
The exterior of the DT NO.1 DT99 was inspired by the Amazfit GTR, but the difference is noticeable. It is a metal smart watch which is available in several colors and with a metal leather strap. It weighs 59g.
The IPS’s touch screen is a pleasantly large 1.2 inch 240 x 240 pixels resolution. It is a round display, so not just a rectangular display is placed in the round watch face. The clock face is changeable and there are quite a few.
Moderately waterproof, if you get a little more water, it won’t hurt, but you may not want to put it in water for an extended period of time.
You do not have a genuine operating system (such as Android Wear) and the firmware is responsible for its operation. It also comes with a mobile app (Android, iOS) to help you set up and use it more efficiently. Some functions can be used without any extra equipment, such as pedometer or heart rate measurement, sport modes. The collected data can then later be synchronized with your mobile phone and tablet.
This is fine as a watch. As a health and fitness device, it's an inadequate fraud.
All readings are the same for Ecg, BP an he – whether reading off a piece of wood or your wrist.
Pedometer is extremely in accurate too.
Build quality, message receiptand handling are good
But this is not an authentic fitness or health tracker. Gosh, it even confuses diastolic and systolic BP – which takes utter stupidity to achieve.
