I can only recommend this wall mount, it is easy to install, keeps well and sees if there is no tablet is it chic enough from order not to disturb the overall flat picture. The back of the iPad (in my case have an iPad 2) is working properly, it is tight and also looks quite good. The interplay between iPad back top and key "puck" works without any problems, even here everything is secure when it is hooked, but can also solve problems via the two buttons.
All in all I can only recommend this product because it perfectly fulfills its purpose for me and this also looks good, exactly what I was looking for.
