Well, after YEARS of struggling to find the "right" cages..(trust me, in the 70's and 80's, you knew the struggle of the aquarium or converted bookcase enclosure)...I took the plunge and for my birthday ordered some Animal Plastics cages. I got 9 total, 5 of the Carpet Cages and 4 of the T-3 cages.
My impression thus far: the material is really nice, strong, but very lightweight. The fit/machining of the material is outstanding. Every single screw hole lined up...freakishly well. The assembly was a breeze. I put 9 cages together in about 4 hours. I got the recessed LED lighting, which is an exceptionally nice feature. The acrylic sliding doors are thick and sturdy (more about that later)...I do wish they would route a place for the heat tape rather than just aluminum taping to the bottom of the enclosure though.
The customer service was good. I had great communication w Ali at AP, and she walked me through the whole process, even when I made a couple of changes in my order. The time to ship was a little rough (mostly because I really just wanted my cages!)...The 8 weeks turned into a little longer, but in the end, the order was completed and arrived via freight completely intact.
Here are a couple of pics so far. The cages are sparse, I haven't completely furnished them yet. There is a nice gradient (based of IR temp gun) achieved just with the heat tape. Unclear if I'll add RHP or not.
You can see the shims I've used in the sliding doors...That is one weakness I can really have concern about. The doors do not seem secure. With the way the relics rub, I can see them nudging open the door and escaping. I tried the trophy case locks, but the center piece prevents it from working well. The shims are effective and cheap!
