I have one of the exo terra explorariums. It is a nice high quality cage. The netting is a little tougher than most net cages I've seen, probably because it was made with herps in mind rather than just an insect cage. The weave in the netting is also a little larger so not a cage you want to use small fruit flies with but everything else should be fine. Because of this most of the mantis turds will also fall right through the bottom weave, but a lovely plastic bottom is included to go around the outside so it makes cleaning easy since you can just pull that off and dump the waste then put it back on.
I like the fact that when it hangs the top isn't flat but goes up in subtle slop. The zip door could be larger. It can be a bit of a pain trying to get sticks in and remove mantises.
Overall however I still prefer the Live Monarch ones. It is nice to hang the Exo Terra ones, but I find the white mesh so much easier to see stuff in and you can't beat the price.
