+ Super design. + Super big. The unit is about 19 cm long. + Blue color of the numbers (looks modern from). + Great buttons and functions. - Display is something bright - even when the brightness remains a matter of taste. I found the brightness also a bit disturbing. My solution for the brightness was (TRY THIS AT YOUR OWN RISK I'm not responsible for the consequences!) - The 4 screws to take out on the ground, after which the case can be opened easily, then 4 layers (folded for example) of a black mosquito net (6 layers are probably even better) Attach with adhesive tape on the screen, close the housing with screws. The danger is - next to the display is a hot transformer, causing the network or the adhesive tape can be heated. With the network, the device looks now still futuristic (better) out.
Tip for developers: in such devices in the future a continuous rotary control regulation for brightness attach (rather than a dimmer knob).
