Welcome to the forum lake36
I have the QS4 and use the standard T wall bracket that comes with the purchase of them. I initially had them installed on the walls in my bedroom. Obviously they leave holes in the wall when taken down but it is easy to fix. For renting purposes (if allowed) before you leave all you would have to do is buy some plaster, fill the holes, let the plaster dry then sand it down. Take a chip of paint off the wall and bring it to a paint shop for a colour match, then buy a small can and touch up the walls....easy
If you decide to use the T wall bracket, make sure to install the screws into studs in the walls.
