Hats off and congratulations to the developers of the board or the buyers of the Far East goods !! How can you only so bring a waste on the market? The board is only suitable for professionals who never miss the fields !! An arrow on the keypad absolutely cheap (!!!) and the part has a hole. But what is even worse: in our case, by the electronics were so badly damaged that no longer worked. Conclusion: scrap absolute misconstruction. A star is still way too much.
