I ordered this to mount a Galaxy 8 tablet in my work truck. As they say, only as strong as the weakest link. The weakest link in this design is the actual component that needs to be the strongest, the base mounting plate is made of plastic. There is no way this will last for my application supporting a full sized tablet in a bouncy work truck. The rest of the holder is made of heavy rugged plastic. This will be fine if using to hold a cell phone but not a large tablet. If the base plate was made of aluminum this would be a winner.
