Strong enough. Good quality. Indoor waste bin, ok and fixing ring for efficient bag. Reliable: detects relatively well the difference between a passing nearby and an open request. By cons, when I have to really go over many times because it is below the open field of a cabinet door where my fridge boxes is, I push the General button on the back to off because 2 times I used the off button on the front, he lit the lamp to signal the support of the order, but it was ignored. I have perhaps not understood the sequence to perform. I will review the user manual. But even if that is the case, it does not deserve star less.
