Rated 1 out of 5 by from Visi-therm heater stopped heating or defective I purchased this heater at Petsmart where they still carry. They want you to ship the defective heater before they send you a replacement. It is more than to pay for shipping than buying a new heater. Not to mention that some consumers live on the west coast. They are defective and need to look at the problem.

Rated 2 out of 5 by from Works great as a heater, but I'm really concerned I just bought this heater from my lfs about 3-4 days ago. I spent about 25 us dollars. Literally the next morning after I had got it in the tank and running, I noticed some condensation. It was only a little bit, so I figured I'd wait to see if it would go away. Now, 2 days later, there is just a ton of moisture inside the heater. This is literally why I replaced my old heater, because it was getting moisture in it after a year. Now this one has more moisture than the other ever had, in less than half a week! I will never buy this heater again.

Rated 1 out of 5 by from Avoid these heaters. I bought two of these about 4 years ago. After about a year, the first one died - light would come on, but no heat. It was replaced under warranty. The second one died about 6 months after that. Again, replaced under warranty. The first replacement one died about a year ago, and was not replaced. The second replacement one died this morning. In all cases, the light came on but the heat did not, making it less likely to have the problem noticed. These are great heaters - for the first 6 months. They are not designed to last. I would strongly discourage anyone from getting these.

Rated 1 out of 5 by from Short Lifetime Model ML 90651. Worked for about a year. Now doesn't heat. LED blinks once every 5 minutes or so. By the time I package it, take it to UPS, pay shipping (2 directions) it is not worth it to bother with the warranty.

Rated 5 out of 5 by from Precise temperature Great heater that enables you to dial in a fairly precise temperature and also can double as your thermometer. Again, just a quality product from Marineland.

Rated 1 out of 5 by from Great visual design, poor mechanical design. Purchased the 300 watt visitherm heater for my new Marineland 75 gallon tank. Purchased specifically because I love Marineland products and the visual temperature gauge and the really nice temperature dial. Placed it in my new tank to stabilize the temperature before I transferred my fish from my smaller tank. Heater was working for two days but water was not heating up and a day later the heater stopped working altogether. I don't mess with electrical appliances regardless of the simplicity. Perhaps this one was just a dud but I was really disappointed it stopped working. The real pain is dragging myself back down to Petsmart to exchange it. And of course, there wasn't another one in stock so darn. Went ahead and used my old heater but it's not big enough though the water temp seems stable for now.

Rated 1 out of 5 by from 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.
