Although the electric suction cup mounts are quite effective at what they do, they are electric so they can inherently be more noisy when the pressure starts to loosen up. Meanwhile most of the normal suction cups tend to just let go without prior indication, this one gives you the peace of mind of not only when the suction is strong enough when setting up, but also when it starts to be loosen.

The first time using this I had trouble getting the suction to work properly. After pfaffing around for a little it finally started working and oh boy does it work well. It works so well that you can still get some decent results on painted gyprock. At the base the strength it can hold up is indeed impressive, though with more of an arm extended away from your mounting surface it will cause the suction to be less strong. In which case, staying with very light weight equipment is best--if you had to use heavier gear like a smaller mirrorless camera, either the mounting surface should be horizontal, or you should keep the magic arm very close to the mounting surface.

The magic arms themselves do work pretty well but it also can struggle with heavier loads, so in terms of how heavy it can hold will be in a similar recommendation as the suction mounting itself.

Unsticking the suction cup once it is properly placed, thanks to the visual indicator, is a little difficult still. Good thing the little protruding bit on the suction cup does a good job at helping you break the seal.

Overall though, this is a pretty impressive kit if you are looking for something of a manual suction cup accessory with a manual pump for added security. Thanks to the mounting holes you can also change what and how you mount things to it, as well as using multiples to attach larger gear. For how well it is made and how effective it is, this is a pretty well priced model that can very easily be recommended.
