### ⭐⭐⭐ Good, but has some flaws...
*by E***G on September 4, 2017*

The product has 1 big flaw. Not everything on the head-unit is in English. Some is in Chinese which is really annoying. One cannot change this anywhere.There are some other smaller issues. One just have to live with them:(1) The quality of the coating on the valves (the part that's on the outside of the wheel) is not good quality. Its a very rough coating which attracts dirt extremely quickly and it will not last over time - my prediction. They should use some kind of stainless steel to manufacture the valve body.(2) The screen is not bright enough. During the day its kind of difficult to read the screen.(3) The sensing of the sensors is a bit slow to my liking. This can also not be adjusted. Sure they want to preserve battery, but I specifically bought the units with replaceable batteries.The big positive about this product, for me at least, is the wireless nature when used permanently in the 12V socket. Its plug & play. I just wished that all could have been in English. The other things I can try to live with...Thanks
