Great product! My temperature used to swing +-1 degree with my old heater. Ever since I put my new neo therm heater in my swings dropped to +-0.2 degree. Very accurate, indestructible, small footprint and easy to read thermometer.
Leaks Voltage By Worm5406 on 1/21/14

I bought 4x 200 watt versions of these. I have now had 2 of them die and leak voltage into the tank. They not only leak voltage they both would not light their own lights and even show they were on. I took a voltage meter and tested it numerous times, and replaced it and the 90VAC in the tank disappeared. I would understand one... but two within a week time span in unacceptable.
I have had one get a thermal barrier around it in bubbles and stop heating.
I do NOT think these are what they are cracked up to be. I had high hopes for them but with 50% failure, I am sure I will be sending them all back and switching to the old standby, glass... Even though I do not wan to, I can not stand being shocked.
After I left the two bad ones outside the tank they turned back on and stop leaking voltage.

I am very happy with this heater! Easy to set up and I like that it shows if the temp of the tank is above/below the desired set temp. As always,great service from bulkreef!
Worth the cost over other heaters By Chris on 12/9/13

Love the Cobalt heater- although it's rather expensive in comparison to other heaters like it, the quality is 10x better and it's a small investment for keeping your animals healthy. It's also the first (and only) heater that I wouldn't mind seeing in the DT, it's super sleek!

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!
Great little heater! By Chad on 11/9/13

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!
Super Tight Range By dac on 6/16/13

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.
