Product does not work more than 2 months I bought the 300 watts heater cost between 50-60$ 2 months later just stopped working. Light on but not heating called company they replaced it 2 months later same problem called a second time. They agreed to send another But I was told by customer service life time warrant does not mean life time warranty and if it breaks again it will not be replaced( life time warranty means life time) . Very disappointed if marineland would make a good product I would not have to keep going through this. I have other heaters bought before this one all still working. Date published: 2018-02-20

Faulty safety shut-off I pulled the wrong plug when doing a water change so the heater didn't get unplugged. It was about 50% out of the water when it turned on, completely melted the plastic mounting bracket, but the safety shut-off never tripped. We unplugged it and carefully removed it from the tank, then went about pulling the strings of plastic out of the water. Yikes. Date published: 2018-02-16

Love the new look! I bought one of the old Visi-therm heaters about a year ago for my 10 gallon and when that one gave out on me I e-mailed customer service and they responded within one day and helped me get a new replacement heater. So far I love the new design, the black looks alot better than the light grey with the color scheme I have. And it isnt the most "accurate" on teperature -hence why I'm only rating it 4 stars- but then again my last one wasn't perfect either so can't complain. Date published: 2018-01-14

Trouble w/ 400 Watt Heaters I've purchased two and both have condensation INSIDE the unit within a week. This is extremely worrisome to me. Date published: 2018-01-01

1 month? I purchased the 400w and it only lasted 1 month. Pretty frustrating when you have a reef tank and have your temps drop overnight. Date published: 2017-11-23

Guarantee Great company. It did poop out at plug after about a year, but they replaced it, no questions other than "what is your address?"! Valerie Date published: 2017-10-06

Junk I have had aquariums for 40 years. It seems all products have been cheaping out over the last five years and charging ridiculous prices for this non funtional product. These are no exception. I have had it for less than a year. Clearly the seals are no good. The temp hasn't been steady and it started whistling about a month ago. I bought a different brand heater and we will see how that goes. What good is a lifetime warranty if you have to just get another piece of junk from Marineland. I am going to attempt returning to the place of purchase for a refund. Date published: 2017-08-07

Heater failure. I've had this heater for a little over ~7 months now and it worked great. Until recently I noticed my fish getting lethargic. I felt the water and it was extremely cold. The heater has not warmed up even after unplugging, turning up the heat and down and I believe it has failed. It hasn't even been a year with it. Date published: 2017-05-27
