Excellent strong little heater, won't damage plastic tanks

I've had this heater for about a month now and I really like it! William Betta loves it too! It is housed in a 2 gallon plastic tank (refurbished shortly after it was transferred to that tank) and maintains a water temperature of around 78F. At first I was afraid that the heater would damage the plastic tank, but not at all. The suction cups keep it firmly in place, and the fact that it's fully submersible makes it easy to fit into a tight spot. It's a fixed heater, meaning you can't controlโ€ฆ

Electricity in my tank

It may be that my product was just defective, but I'm sure this heater was putting electricity into my water. The product boiled well and I saw the water temperature steadily rising on my thermometer and was very optimistic about the product. However, when I lowered my finger slightly to see how much warmer the water was, I felt a tingling and burning sensation. Realizing it was probably mild shock, I quickly turned off the heat and tested the water again with my finger. No tingling. While yes,

Pros
  • Decent performance

Study your tank before you buy a heater!

Very slim design. Even in my small round aquarium it almost disappears. The indicator light is a reassuring feature. I love that I can see the temperature and what the heater is doing thanks to the light. My fish don't care. He struggles with the glass thermometer, but the heater is fine. Also, it hugs the glass snugly so it doesn't stand a chance of snagging on it. This is a heater review, but also something I've learned the hard way and I hope someone can learn from it. I have a 3.3 gallonโ€ฆ

  • Quality construction

seems slow but eventually doing what it's supposed to

We have a rooster and the pet store was surprisingly uninformative. When we realized the poor thing needed hot water we got scared and got this heater delivered the next day. We put it on, and it didn't heat the tank for a long time - at least not to the desired 78 degrees. In fact, it took a full 24 hours to get there, so we were very concerned. Now that it's reached that temperature I'll see if it stays more or less there, or if it gets too hot (I hope not!), but so far - so good. The deviceโ€ฆ
