National Geographic™ Aquarium Heater
Adjustable but hard to do so
This is not fully submersible as it states. There is a line to where you cannot go past but its not a big deal for my use. Its nice in that its adjustable up to the 90s BUT its extremely hard to adjust the temp. I have to literally pull it up out of the water and hold it with one hand and turn the dial with the other.

Thank you National Geographic!
You're one of the best TV channels about animals! You make animal magazines, and are basically the best kind of company to make pet supplies!
The heater is AMAZING AND FANTASTIC! The Betta Fish in my 10 gallon is VERY VERY happy! The heater never overheats, or underheats! It maintains the temperature! The coolest part is that you can adjust the temperature!
My Betta Fish is very very happy, because of you! Thank you!
