Excellent price but lousy packing for shipping!
I order 2 aquarium heaters and they threw them in a plastic bag roll it up stuck in mail. Received in beat up condition for a fragile piece of equipment!

Heater is great, the customer service was even better!
As usual Fluval has made a great product that sells for a descent price. The heater works well and looks cool, but when I first received it, the top tab was broken. I called petguys and they mailed me a new one immediately along with return postage. It's hard to find customer service like that these days. Petguys has earned my business for sure.

Works Great
I purchased this as a replacement for another brand. It arrived on time and as described. It is well protected from my aggressive silver arowana.
Prosidiot-proof temperature indicator, easy to read, telltale colors
Consa detachable display would be nice
