Orlushy Submersible Aquarium Heater,300W Adjustable Fish Tahk Heater with 2 Suction Cups Free Thermometer Suitable for Marine Saltwater and Freshwater

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.

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.

Keeps a nice even temp in my tank.

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

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.

Love it it works great for my tank the thermometer reads great internally the display is externalThe heater is fully submersible and easy to install

Easy to use, works well, it warms the water up within 2 min!

Works great. Good quality. The only complaint is that the digital thermometer that came with it is inaccurate. Don't bother using it as my reading was about 2 degrees off.
