I ordered my first batch of Queal last week, and it came with a nice lil' shaker.
The quality is great! I was a bit worried that the plug might unscrew in my bag, but so far no troubles. I do have to say that I also have the issue of the plug "spraying" droplets when I open the bottle, due to some kind of pressure difference. I'm aware of it, so I try to keep the bottle as far away from me as possible, but it's still a little annoying. Doesn't matter if I open it slowly or in one go, either.
As for cleaning it, I've found a way where I don't need to fold my hand up like origami to fit into the bottle. I simply fill the bottle up with hot water and some dish soap, pop the wire ball in and give it a good couple of shakes. Then I drain the excess foam and some water, and shake again until clean. Works like a charm!
