I haven't used them personally....
they look similar to a lot of the tubs you see in the food industry. I've also used something similar looking while working a big box pet shop.
If it IS the same type of material.... It'll be easy to clean and sterilize. Obviously very easy to see the animal in, so good for qt racks.
They can be scratched but typically takes a very hard item to do it, vs the standard which can sometimes get a rough texture if you scrub too hard on it. The downside would be that they are easy to break corners on if you drop them the wrong way, so you can't throw them around like regular tubs.
