Wont become loose or wobble
Very small, so the hopper isnt too high when peeking
When its screwed in, it'll stayin
When the allen key is tight enough, it will not budge
Some may say the allenkey-tighten system is a weakness, but I think its better this way,
some other push-to-lock systems may have rubber or grated grips which dont work at all.
The tightness of the rotating clamp keeps the hopper in place, very effective.

I honestly cannot see how this product will fail me in the future, it doesnt have clamps or levers which could be broken off, or grated metal/rubber grips that will wear off.
The allenkey locking system may seem a bit troublesome by other reviews but its definetly a + in my book, compared to levers and hand held screws it cannot fail you.
