Yeah, those are Vision cages. I bought a few used from Pro Exotics, for about 50% of new.
My biggest complaint with them is they dont have a flat bottom. They have 2 ridges to keep them stacked together, and it can make them a little tough depending on the substrate you use.
They are not too bad to heat if your ambient room temperature is high, but in a cooler room I had trouble heating the whole stack evenly. I finally wound up building a shelf unit to hold them and the temps are much more consistent top to bottom. Also the heat does not have to run as much to keep up.
For the price I paid for them they work well.
