I bought a very similar one from a pet store and it worked fine. ) 2 extra stars for the return process

1 star for the product- it did not work at all, either it was glued together backwards or there was something defective with the syphon bladder. (It wasn't user error, I bought a very similar one from a pet store and it worked fine. ) 2 extra stars for the return process. I had to send it back, which is annoying(but understandable). I guess I've been spoiled by sellers who don't require the broken item back ;)
