So I wish I'd started with these when I FIRST got into BP's. IRIS tubs are amazing and sooooo easy to clean!
I used a soldering iron to melt some ventilation into them because I live in a pretty high humidity area. They have NO grooves for poop to get stuck in and all the ones I've bought have pretty decent visibility. I feel my babies are more comfortable in these with some newspaper curved up the sides. My fav part is they are lightweight and SO easy to drag into the tub for a good hosing out. If you have a spare, you can just move over cage stuff and put the snake in the spare rotation.
I admire anyone who keeps their BPs in nice, clean tanks with beautiful substrate and hides, but I have too many... and I'm LAZY!!! XD
