My boyfriend loves these shoes had no idea of the brand but when I told him of all the stuff it is supposed to do he was very impressed. Ive had no problems with the battery draining before I wake up. They?re probably better for a photo shoot or a sitting event. I sprayed those with wd40. 5mm for my Xbox One controller, and a banana Y splitter adapter for PC sound cards with microphone input and audio output. In the end, I am very impressed. It was ready to test! I can use it in my convertible. This is the main reason Im considering buying another cover is that the cover always gets hair, plus the dust it catches every surface it touches, and when you close it makes the screen dirty. She was so surprised I ordered them.
