I've got 4 of them - they're great filters for the price. I've had great experiences buying from the eBay vendors. They are quick to resolve problems. I should probably share the problems I had
I cracked an elbow piece setting it up - they sent me out a new one free of charge. I bought one that didn't have the surface skimmer pictured, and so it didn't come with the filter. I had just assumed they all came with the surface skimmer piece. They sent me one anyway, free of charge. I bought one that leaked out of the box. After some trouble shooting, they sent me out abother and told me to keep the leaky one, free of charge. Since I have 2 filters in use of that model, it's nice to have some extra parts.
