The top will not stay on, I even used an adhesive promoter, the first 3 times I found it, but this last time, it’s gone for good. best if you hardwire cause it has no battery for times you not in the car , to use motion detection. I love this phone mount. Fit was perfect, based on the Amazon sizing chart (which undoubtedly saves a lot of returns). For this low price, I expected a lot worse. Oh yeah, I almost forgot, theyre 20% CHEAPER to boot! Great price and like the color choice available. so maybe I just got a defective left slipper. Malgré sa petite largeur de 65 cm, on peut mettre 3 paires de chaussures dadultes style basket par étage soit au total 9 paires. Id very much recommend them as a cost effective solution for gaming with headphones.
