New is the 0.95 inch large touch display. This is of the type AMOLED and now also represents colors (24bit). The high resolution of 240 120 x pixels ensures a crisp, sharp image with a low display diagonal. Special features of the AMOLED are the particularly strong colors and the almost infinite contrast. When black is displayed, the pixels that light up are simply turned off. As a practical side effect, the energy consumption of the panel is reduced.
By the high Display brightness of 400 Nit The display remains very readable even in the sunshine. Overall, 5 brightness levels are available. What the display unfortunately misses is an automatic brightness adjustment. The panel is protected by a hardened protective glass. The 2.5D Curved Cut ensures rounded edges and a better look. The capsule-shaped tracking unit is removable and is connected via a 2 pin connector loaded. The charging pins are now on the bottom, so that the charger of the predecessor in contrast to the bracelet is not compatible! The fitness bracelet is waterproof to 5ATM (50 meter) and can therefore be easily worn while swimming.

The What's in the box includes the TPU wristband, tracking unit, USB charging adapter, and instruction manual.
