Seems to work as desired. Just ordered a second one for my aquarium. I've now updated this review because my second heater came (as a backup) and now the first one I ordered just shattered in the tank. Can't think how that happened but the bottom blew out of it so there is glass all over my rocks that I have to fish out. I can't remember bumping it or anything but just a heads up that they are pretty fragile so take care when installing or changing the temp.On another note, these are fully submersible so with that said if you choose to utilize them in that way it gets tricky to change the temp up or down because the knob is pretty hard to change and nearly impossible under water hanging off the back of your tank so you have to turn it off, let it cool for 15 minutes and then remove it from the water before adjusting the temp...kind of a pain but if you can get the temp dialed in you should be good to go. I'm now ordering my third one in three weeks. LOL

    Worked great until it cooked my tank
  

*by K***. on Reviewed in the United States on January 8, 2018*

This heater is slightly confusing with the temp in Celsius, but I figured for the price I would give it a try. It worked great for about 18 months. I know I should have replaced it at that time, since it was in a saltwater tank and that is about the heater lifespan. I didn't. It ended up cooking a good amount of my coral. When this heater broke, it remained on and HOT. The temperature got up to 88.8 degrees. So while it worked, when it failed, instead of being good and just not heating, it drastically overheated everything. Side note, I've had better luck with livestock and corals living through a cold wave when a heater dies vs a heat wave.

    Waste of money
  

*by B***N on Reviewed in the United States on September 7, 2016*

Came with directions and a temp. Chart. it recommends you have 2 heaters in your aquarium at all times. I've never heard that before and I have 2 seprerste fish tanks. After setting them both up only 1 works. So it made me wonder if they sale 2 then maybe That's because they expect one to have problems or not work. Then one that works does a decent job though
