I have 3 of them filtering my 150 gallon aqua-glass tank. They have been in service on said tank for about 9 years or so. Never an issue, and they hold up very well. So well in fact, that I will generally go a year before I break them down and replace the media and sponge. They are affordable, rugged, and the only complaint I have is the quick connect compression fittings..it's a real PITA to hook up and not have leak....But If ya for-go the quick connect hardware, and hard plumbed one in, I think you would be quite pleased.
