Works for Syrian hamsters
First of all, this product appears to be well-made out of a very soft cloth material.  Basically it is a half-tube in shape that wraps around  your head to put your animal in.  I was skeptical that this would work for our Syrian hamster, given that they are always on the move and I thought that he might not tolerate being in the carrier.  To my surprise, my hamster seemed to enjoy being in the soft material.  He walked around the carrier from front to back if I left him alone, but I could also gently hold him in the front part of it so that he didn't wander off to the back.  He stuck his head out of the edge a couple of times, so you have to be vigilant that they don't fall out, but, again, that was to be expected, given how curious hamsters are.  Despite all of that, I was able to walk halfway around the block with the hamster in the carrier with no problems.  I think this carrier would be useful if you want to go out and about with your hamster, want to get him some out of cage time while still doing other activities, like working on the computer or reading.
