Rated 1 out of 5 by mememe Not accurate at all
Want temp in the mid-upper 70's..... Heater stays on all the time until reaching 8284. Lower temp setting to 72.... Still heats to 84. I know its the heater as you can take it out and its hot.... heating even though tank is well over 80.

I have used Visi Therm heaters in the past with no problems. As wells many other Marineland products on all 7 of my tanks. But quality control must have been fired because the new ones are horrible.
I'll start From the beginning...
This past Saturday I went and bought a 75 watt heater for my 10 gallon tank. I know it's a bit overkill, but I'd rather have to much than not enough heating. I brought it home and put it in my tank over night. The next morning I plugged it in and went about my business letting the water heat up. Later once the tank was the right temp, I put my fry in their new home. The next Morning I woke up and the tank was 96 degrees. The T-stat was set on 77. I tried to turn it down think it just wasn't calibrated right but I could not get it to shut off. I promptly took it out of my tank and put my small back up heater in there to at least keep them from freezing or suffering stress from a fast drop in temp.
I called Marineland about the issue and she was very nice and understanding about it, but since I just bought it, I told her I would take it back to the store rather than her send another one to my house. I took it in and exchanged it for another one and it did the exact same thing. That evening I took #2 back and got a 50watt this time since thinking it was maybe a production issue with that batch.
The 50watt seemed to do the job at first, but no. It just took it a little longer to over heat my tank. I pulled it out when it hit 90 degrees.
3 heaters, 2 different wattage's and the exact same problem with all of them. After issues I had with a filter from them, and now heaters too? Someone needs to step up and restore the company name to what it was. Until then, They lost a loyal customer.

Rated 2 out of 5 by Tom2sail 50 % success rate is not good enough!
The quality control of Marineland submersible heaters leaves much to be desired.
We bought 2 - 250w submersible heaters for the same tank and 6 months later one works, one doesn't. This is the second time I've lost a Marineland heater in a year or less and it's the last. 50% doesn't cut it. Overall success rate for me, 33%.
