  • Best heater over the past 7 years, I tried.
Pattern Name: 300W
I use this to keep my 150 gallon turtle pond warm during the winter. In Hawaii, we don't get too cold, but cold enough for my red-ear sliders to suffer. This little heater works wonderfully and keeps the tank perfectly warmed for them and doesn't "strain" to keep the pond warm. I tried several other heaters and they all burned out within a month, but this is going to be year 3 for us. I am delighted with it. ... show more

  • Small aquarium heater
Pattern Name: 25W
Works well even though I turned it on before the water was added and it partially melted the heat cover. I should read the directions first. My problem, but glad it still works well.

  • Even Temp

  • Overtemperature problem.
Pattern Name: 300W
Product does not have any form of over temp protection. The one time I forget to unplug it during a water change it begun to smoke and melted the holders. I never had any other problems with it otherwise and I'd still recommend it. Just place it lower in the tank if you're forgetful.

  • Great Purchase
Pattern Name: 150W
These heaters are really reliable and last a long time. They are a decent price too. It’s been almost 2 years and I’m still running mine with no issues as of yet.

  • Nice temp control
Pattern Name: 300W
Keeps a nice temp but my only complaint is it does get hot to the touch. My last one was much cooler to the touch but didn't operate as well. hmmmmm
