I upgraded from an Animal Plastics 4'x2'x18" enclosure of a similiar style. The build quality on this is better, the customer service folks actually get back to you (I had been trying to get replacement doors on the aforementioned AP enclosure for over a year with no traction), and it ships flat rate apparently (I thought this was proximity based, but was informed that it wasnt, it's just flat rate). I'd seen alot of videos on a certain facebook contributors tortoise page and thought they looked sturdy. They are. And when you're buying something this big (8x2.5x2) shipping becomes a concern. Some competitors are charging the same price as the unit itself for shipping. Thatd be about 3k for this unit. flat rate cost me only about 300$ in shipping on this instead. That's what really sold me. Its definitely worth the price, but I wasnt about to spend the cost of 2 of them just to get it shipped from a competitor. Packaged great, easy instructions, did need 2 people to put it together because its BIG. If you're in an apartment this could be tricky because they deliver curb side. and you arent going to be able to just pick up the box and drag it upstairs. It has to be unpacked where it is dropped off (my garage is where they dropped mine, so no issues getting it unpacked from there). May also want to get some furniture dolly's to move the pallet if they dont drop it where you want it (says curbside, the guy was probably just being nice and put it in my garage). I had bought 2 Animal Plastics cages over the last 20 yrs. Wont be going back. This is where it's at. also bought two 48" luminize fluorescents from Toad Ranch. Good as well!
