I've had a really nice stainless commercial type pot for years, and that cheap Danielson collapsable outfishes it 3-1...I think those simple doors right on the bottom make it easy for them to crawl in....They have no weight, so you need to weight them or they will move, and either get lost, or catch nothing....I put 2 old window sash weights in each pot, and they stay just fine. A moving pot catches no crab, and a lost pot is bad juju...Tom
