I think the screws for the back panels could be smaller and more aesthetically pleasing, but thats a minor concern. The price lost another star. As far as the unit itself, the build quality is really good. As soon as I rinsed it off my face was bright red, stinging and felt tight & dry. The pairing was very easy with my android phone and never had any issues with the phone cutting out. Aún no las usa, esperemos que sean de muy buena calidad. wanted to return but I have already opened the box. Don?t buy it. I had to buy screw in anchors from hone depot to ensure these wouldn?t rip off the wall, when you have heavy coats/wet coats during winter. I do find that they wide in fit, but super comfortable.
