I bought this heater in December of 2015 and did not even open it until March 2016. I submerged it underwater and waited 15-20 minutes to turn it on like the directions said. I turned it on and it began to work. I left it for a few hours and when I came back I smelled something burning, then looked in my sump and saw that the heater had shattered into two pieces. Maybe it was damaged during shipping.
Not worth the money By jayden on 8/15/2015

The heater is great for heating the tank up but it is very hard to tell what you have set the temp at. Also it seems the the heaters temp prob is off because I have to have the heater set in the 84 degree range just to have it heat the tank to 75 degree. If I had the chance to get a different heater instead I would have gone with the flat cobalt heater with the two led lights. This heater has way more control but it is a little pricey. All in all if you really care about your fish then save up the money to get the more expensive heater. (Was not payed to right this for the more expensive heater)

Never Even Got A Chance To Get It Wet By Jordan on 2/21/2014

This was one of those purchases where it was something I didn't need but wanted to have just in case one of my heaters broke or I needed to use an extra one for heating more water. When opening the cobalt box, the box itself was in perfectly fine condition. However a shard of glass about half an inch long fell out of the box. The plastic piece that cups the bottom of the heater was not attached to the heater which some where along the line caused it to get cracked inside the box. The heater was obviously no good with a hole in the glass. Compared to two other glass heaters I have, this one seems much more fragile. This will probably be the last time I buy a glass heater.
Early Failure By Dr Allison on 2/5/2014

300W model lasted just over 3 months. I find that completely unacceptable. I'm going over to the dark side with a thermostatless heater so this is never a problem again.
