Beware! Glass Broke while in Tank!
I received my heater on the 20th and it was in good condition and worked great. It kept the water temperature at a set 78degrees….BUT TODAY….only 6 days later, when I was doing my 50% water change, I came to find out that the glass had popped! Fortunately non of the glass had broken off while inside of the tank. Only once I removed it, did it finally fall apart. I a very disappointed that this happened and my husband and I do not understand why it happened. It was placed by the filter so that a constant flow of water would move pass it as recommended. So what would cause it to pop. In my opinion, it is really unsafe for aquariums.****UPDATE****Two days after posting my review I was contacted by the Mylivell seller though email to rectify the problem. I am highly satisfied with their costumer service and professionalism. They were very sincere and prompt in their replies. As of right now, I have the new heater in our 36gal. It has been six days since the setup of our new tank and the heater appears to be doing fine. Just as the previous heater did, this one is also keeping the water at the set temperature. My husband and I genuinely hope that the popping of the glass tube on the previous heater was just an isolated event and will not happen again. But If another issue should occur I will be sure to post an update.1/17/20

Great deal
Good deal, works great and turns on and off correctly when it gets up to temp.Temperature settings knob is a bit confusing but works as intended and looks really good in tank.

Not raising temp above 72 in a 15 gallon tank
100 watt Mylivell heater not raising temp above 72. i have checked with thermometer comparing against other tanks so the thermometer is good. I have changed electrical receptors. I’ll have to put old 50 watt heater back in.On Dec. 16th they said they would send a replacement. As of Jan 9th I have not seen a replacement or heard from them again.I did receive my replacement and it works great.

Terrific aquarium heater
I have this Mylivell heater in my 10-gallon aquarium. It is very accurate, easy-to-use, and hasn’t budged from the spot I put it in originally so the suction cups are great. It keeps an even temperature in my tank and performs flawlessly. I am very happy with the product.

Good quality for the price
Lasted 4 years and it finally stop working. Pretty good for the price so I ordered another one!

This has been working great for over 2 years
I got this a while back but didn’t bother to review it until now. Initially I was worried about all these off-brand aquarium heaters that significantly cheaper than their more well-known competitors. Quality control is a serious issue for those who are buying equipment to take care of a living animal. Amazingly, this heater is still going strong at 78°F and I haven’t had any problems with it overheating or breaking apart.Though I’m not sure this can be said the same for everyone else who got one. There will always be defective units so I’d make sure you put this in an empty tank for a week just to make sure nothing is wrong at first.

They can be good but unfortunately they can be bad too.
Sadly three days after the return window closed, the heater is heating my 36 gal tank only to 72 even though I have it set to 84, I bought the 50 gal tank heater so that it wouldnât have any problem heating it. But alasâ¦. The other one I got from live well is working without a glitch.

This fish tank heat works great. I love how you have the temp in °C/°F. It has big numbers and a red mark that spins as you turn up and down the temperature so you can easily make out as well as a red light that turns off and on to let you know when it’s heating up or not
