Good performance for the money I have bought three of these over the past year and have been impressed by all of them. Unless you plan to spend $200-$400 a piece for the eco-tec units, this is a darn good value. They may not have all the bells and whistles like other models, but they are dead quiet, and when I say dead quiet, I mean that with everything else off in my reef tank, I have to put my ear four inches from the water to hear it running. It also provides a broad current, which is desirable, as opposed to a concentrated jet. Is it the absolute best model on the market? No. Is it the best value? In my opinion, yes it is. For anyone on a budget, these are the way to go. Oh, and when you put it on the tank, it stays put! Most models I have seen have had a tendency to “walk” down the glass over time (these do not). – 125 Gallon glass mixed reef tank.

Dont waste money on a powerhead for circulation…get this! Wow. Ive had this for 2 days and come away super impressed. Casts a wide spread that works perfectly in my 55 gallon saltwater tank. A powerhead will seem puny compared to this if you’re using it for water movement. At the same time, because of the wide spread, it’s not overly powerful in any way. Build quality seems super sturdy and it’s super quiet as well.

Nice but not perfect. PROs:- more powerful than powerheads that blow a jetstream- agitates water surface yet doesn’t blow my sugar fine sized aragonite sand around (I hate getting sand dunes where eventually I’d see the glass/acrylic bottom of my tank).- magnet holder- medium length cord- low 4.5 wattsCONs:- Starts in reverse then I’d unplug it and plug it back in then it works.- kind of big compared to Ecotech Vortech MP10 and Aqueon powerheads- doesn’t blow as powerful or as wide as my SEIO m820 powerhead- isn’t as adjustable at right-angles like the SEIO m820- I bought 2. One is working great after 9 months. The other started buzzing from the motor after 3 weeks.7/1/2013 update: the magnetic impeller cracked after 2 years but you can buy a replacement on Amazon or call up Hydor for a free replacement. I’ve dropped my rating from 4 stars to 3 due to reliability issue.
