Has anyone used the topfin pro 120 or 200 canister

I have noticed that petsmart is selling their rebranded eheim canisters and was wondering if anyone has experience with them and if they are reliable as the eheim versions. If so it would be a great deal on an amazing filter.

Never even knew it existed.  

But are all the Eheim filters equally reliable?  I was always under the suspicion that the mainstay, super-reliable one is the Classic...all the others are sort-of "lesser" in terms of reliability/performance and were mainly released to compete with other brands trying to "perfect" the canister design.  I think the steps to "perfect" it or make it more user-friendly directly influence the reliability...in other words, the reason the Classic is so reliable is that it's just a cylinder, an impeller, and a motor with some hoses.

But I don't know this for a fact...it's just a thought I developed over years of reading/hearing people talk about filters.  I've only ever used the Eheim Classics (2213 and 2217).
