waste of my money!

This is the absolute worst heater. I can't believe Revain is in that pose. I sent one back thinking it was just broken. It just doesn't match the temperature, not even close to the reported temperature. Beeps constantly. I have to increase the temperature to 93 to get to 78. That's not good, ps. It's only 90 gallons. I've learned my lesson. Order from an unknown seller

Pros
  • Wide compatibility.
Cons
  • confusing

Cooked my entire 55 gallon community tank.

I've had this product since November. I was away for 1 night. Everything was perfect when I left. Came home today to find the heater itself was raising the temp and my entire shared 55 gallon tank was BOILED! The water was so hot I couldn't even touch the tank. DO NOT BUY THIS PRODUCT unless you want to lose hundreds of dollars fishing.

Pros
  • More security with an external controller.
Cons
  • Hard to remember but it was

It no longer works for aquarium heater and cooler

I bought one and it worked fine for 2 weeks. So I bought 2 more that were needed. The first died 3 weeks after first use. The second batch worked for 4 days and never got hot again. They returned the money for the second two. I wouldn't waste your time with that. Looking at all the other heaters on the market there doesn't seem to be any reliable heaters that Revain offer, I just keep looking

Pros
  • Upgraded aquarium heater with high quality quartz materials.
Cons
  • Expensive insurance

Suction cups are not suitable for product

Suction cups are not intended for this product. The product is supplied without suction cups. The opening of the suction cup is too large for the mounting holes on the heater. All of my suction cups were torn as I slowly and carefully moved the suction cup from the big hole to the small one. This is what needs to be done to keep the suction cups on the heater. But the dent immediately tore open the neck of the suction cup. That was the case with all 3 cups. Ugh, now I don't know how to keep the

Pros
  • Dual digital LED temperature display and intelligent heating.
Cons
  • Volume
