This is hands down the best heater ever. Compact, accurate and so easy to use. The display is clear, the slim design fits in tight spots, and it seems to be indestructible. It is not a fragile heater!

I bought this heater because of its dimensions. But it turned out to be one of the best heaters I've owned. This fits perfectly in the inTank Aquaclear 70 media basket. It holds the best steady temp of any heater I've owned. It's also built to last!

Use a 50w for a 6gallon pico. I picked it up because I was in a pinch when I thought my Aqueon heater broke, and wanted a stronger product. I did not want to pay $55 but it was what it was. I can definitely say it's worth the price. The temperature swings are so stable and tight compared to the Aqueon, which swung around over 1.2 degrees/day. The cobalt is more like 0.1 degrees. And it's nice to have a built in thermometer right on the heater. I use that side by side with a digital, and the redundancy is comforting. It's also basically indestructible, so you dont have to worry about a rock falling and breaking it like with other heaters. I will certainly pay up and stick with this heater series when I upgrade to my 57 rimless.
