Great heater, great price.
Bought the Theo 100 watt heater. Was easy to setup and attached it inside my nano tank using suction cups provided. Adjusted the temperature setting and that is all it took. Very accurate and nice looking too.

Easy to use, works great
Bought this to heat my water before changes. Ended up using it in the tank when my 2 day old expensive heater stopped working. Threw it in the sump as an emergency back up and it has been there ever since. works great.

Very good heater
Very good heater easily keeps perfect temperature in my 75 gallon cichlid tank. No problems so far. It's behind my Texas holey rock and full submerged. Would definitely buy this product again.

Quality product, bought more than one
I only buy adjustable submersible heaters because I am a control freak when it comes to the temperature of my tank. When dialing it it, they tend to wear out with age but with some fine tuning they always get to the desired temperature. I have more than one, and they all work perfectly. I use the 25w-50w on my 2.5 gallon to 10 gallon tanks, along with my brine shrimp hatchery for faster hatching time.
