Product review (4 stars): I wish it were even simpler
I just ordered my second.  After 5 years, it's developed a fizzing leak around the drain valve (which I don't use), so time to replace.  I'm already on my second lid; the first one got radial cracks in the center because I was over-tightening it.
The frame fell apart long ago, I don't crank.  I just toss it a few times like a medicine ball to agitate enough for some pressure.  I use it with a spin dryer, and it suits me just fine.
