This was completely ideal for me. It raised the temperature of the tank (10 gal w/guppies and corys) about five degrees from air temp, so I would often just run it overnight and unplug it during the day, depending upon my needs. I would definitely buy this product again! My only regret is that it can be a rather bulky thing, and doesn't sit entirely flush against the aquarium wall, so it is a little tricky to place appropriately. You get what you pay for, and it does the job. - Note that this is the maximum size of tank recommended for this product! If you have any complicated needs, such as a larger tank, higher temperature, auto shut-off, range control, sensitive fish, ect. then this is not the product for you!

After purchasing this heater I found out it has NO THERMOSTAT (local fish store misinformed me). If your room temperature varies, so will your aquarium temperature! Not good for most fish. The instructions say to unplug heater whenever room temp is 75 farenheit or above (how convenient). The packaging says: "No damage if left running dry", yet the instructions clearly state "Check that the heater never works dry..." Also, the packaging shows an illustration of a hand moving a hot heater into and out of the tank with the words "Super Safe", but be aware that the instructions warn to wait 5 minutes for heater to cool before handling, and always unplug before placing hand in water.

I gave this heater only two stars because I found the packaging and instructions contradictory, and because the lack of thermostat limits usefulness and could potentially cook your livestock.

Using this works best on the 6 gallon fruval edge. 77 degrees lights off and 80.2 with the lights on! No problems under the gravel so far! I had a tetra 10/30 that ran a little warm with the lights on @ 82 degrees so I tried this one. I paid $24 in a store.

It is easy to use and rated up to a 5 gallon...I thought mine being a 6 gallon wouldn't be a problem but this sissy thing bearly heats up at all.

I stupidly bought this heater for a 20 gallon tank. It did absolutely nothing at all. It didn't raise the temperature 1 degree. I set it up right next to the thermometer so I could tell if there was any degree change, and there wasn't. When I touched the heater (after it had been on for a few hours), it didn't feel warm at all.
I'm guessing I had no success because it is a heater for 5-10 gallon tanks and not 20 gallon tanks. However, I also feel like it should have made the thermometer go up at least one degree.
