I love my wall mounted table. I like that I was able to install it at exactly the height I wanted, and I like that it drops down if I ever don't want it set up for some reason.
I am sure if I ever took it down, the holes would be an eyesore. However, renovating our kitchen is in our long term plans, so I'm not worried about holes in the walls at this point.
Did you buy a premade table, or is yours homemade?
