Product review (4 stars): Makes a great critter tube!
Ok, I'm sure I'm not their usual customer, but I was looking for an inexpensive tunnel for my pet rats to climb through. I saw these and the price and immediately bought 6 of them.  They work great for their intended purpose, my only complaint is that at each end of the tube is a sharp end of the wire that is sticking out, so be careful. Also, these smell horrible when first opened, but after a few days out the smell goes away.
