It works

Considering all the 1 star ratings I'm baffled that for 6 years this 200w precision heater has kept my 55 gal at 76 deg. I kid you not! I don't understand? I installed it in my aquarium submerged, let it acclimate, plugged it in and set it to 76 degrees. I made a few minor temp knob adjustments until the water was actually 76 degrees. Each time I do a water change I unplug it and I've cleaned the algae off a few times requiring another slight temp calibration each time. The suction cups did quit suction cupping a couple of years ago but the heater itself continues to function.

Great Heater from a trusted company

I replaced my other heater because I couldn't tell if it was working or not. This filter has a built-in thermometer and a light indicating that it is working. Plus it has a lifetime warranty

Good item thus far. My turtles are happy and warm

I received the item fast and I am using the Marineland one right now and so far it is working great, but I still haven't received my full refund for the Christmas gift cards that I ordered from Walmart and never received as of yet.
