Directions
Instructions
For underwater use only. Use suction cups to secure heater to aquarium. The Flat Heater is designed so that it constantly produces a set amount of heat into the aquarium, it is not thermostatically controlled so the room and water temperature have to be closely monitored during the warmer seasonal periods. Use an aquarium thermometer to monitor the water temperature.

Overall really good! One small detail to note tho!
Works great!! One thing to mention is that if your tank water gets low while it is on it gets this weird white film over it. when I clean the tank I scrub it with a toothbrush and the majority comes off but some stays and doesn't look as nice as it did before. But again, it works great I just have a plant covering mine in the tank lol.

Using this in tanks larger than 4 gallons
I got this heater after reading how hot it gets in the standard size aquariums this heater is intended for. I use it in my 5 gallon and it works absolutely perfectly! Keeps my 5 gallon around 78-80 degrees. So, use this heater in slightly larger tanks since this heater is recommended for 4 gallons and below.
