I have a few Tarantula Crib enclosures, and while I like the smaller ones, the magnets on my 18x12x12 seem overly strong. Not sure if anyone has a large model that has some thoughts? I can barely put the lid back on without scaring the crap out of my tarantula. The tab to hold onto it is not very big to and the magnets cause it to slam shut. I have resorted to putting some foam stripping on the lid frame so it will soften the closure up a bit.
