Nice unit. Adhesive is great, no drilling. Just make sure you have the remote that fits the unit however. The black Apple Remote does NOT fit. I noticed the compatibility chart when I saw it didn’t fit. Suggest putting this in the title. I didn’t even know there were more than one Apple Remote. Anyway, I have their other products and the are perfect. Thank you.

Nice mount, but you can’t have a remote cover

I do like this mount, and it’s super easy to put on. Unfortunately this mount tries to be snug enough so that you cannot use if there is a cover on the remote.
