Can't say much about this puppy, but it falls in to the category of you gotta have one!. Shaking is ok, and I shook bottles for many a year. Truth be known I also turned my two daughters into a press gang for bottle shaking duty back in the long ago. Item works great, and cleans up without a problem. I just take it and stick it into the bottle of brush cleaner and run it for a couple of seconds and that is it. The only thing you should do is to pick out the center part of the mixing paddle. It has s dimple in it that collects paint, so pick it out especially when you are changing color or paint type. Excellent item for the price going to get a spare for the future.

I really like the ease of using this mixer and how it completely stirs up paint bottle. It mixes paint so much better then shaking the bottle. It fits into Vallejo bottle, but is little to big for AK Interactive paints. I ran it sideways on a file so it would fit these AK bottles. I keep a bottle of clean water and run the mixer in it to clean the paint off.

I have used these paint mixers for since the early 90's and these may look cheap but they are worth the $$$. I've gone thru at least 2 and I'm going to purchase another one because It does an Excellent and Outstanding Job on mixing the Acrylic Model Master Paints, Tamiya Paints, and a few others' such as Pactra Paints and my all time favorite: Gunze Sangyo Acrylic Paints. It would be kinda tough if I didn't have several of these Paint Mixers around my Shop. You won't be sorry that you purchased one or more and the $$$ is just right.
