Interpet External Filters

[n-e-w-land]

Hi, Im new here and thought this would be a great place to find things out about this great hobby. I would currently like to add another external filter to my tank to help with the bioload. I have found an interpet external filter, the EPF 350, on the internet for what seems like quite a good price and was wondering whether, if anyone has one, they could tell if they're good or not.

Thanks
