Overall, this is a great unit and, for now, we highly recommend it. I noticed a tremendous difference in my close-range gameplay the very first day I used them. Well constructed ,Exceeded my expansions. All of this would be okay if the price was better. I made sure to wipe the wall down with an alcohol wipe, let it dry, then stuck the hook on with a lot of pressure for about 2 minutes. They give you a little height too as they have a nice little platform We moved last month to our 10th home in 13 years: I have spent a LOT of time hanging things on walls and trying to get the right height and level. 1/5 wouldnt recommend. They just fold closed or open but you have to line up the hooks for the shelves. The dongle gives you control over sound and mic volumes and when to activate the 7.
