Simply Fantastic Design
Date: October 14, 2009
"This product is easy to install and the instructions are not rocket science by any means. I can't wait until my tank is fully setup so that I can test out the heating ability of this product. I have no doubt that I'll be thrilled."

pretty good heater
Date: August 1, 2009
"I bought the 50 watt heater for my 10 gallon aquarium. this is a good heater so far and and it keeps the water at the same temperature all the time unless i move the litte notch on the top, but a little hard to set up when you put the suction cups in the holders, Be careful i had to force them in, but the sucttion is very good!"

Best Heater ever!
Date: June 17, 2009
"I've had my share with heaters. By far this kind of heater keeps my tank at a warm constant temperature. I have had this one heater for over a year and it still works beautifully. It also has a knob at the top, that you can turn to adjust the temperature. This is the best heater I have ever had. I definitely recommend this heater to all fish lovers."

Works well
Date: April 12, 2009
"I got the 50 watt for my 2.5 gallon betta tank.. so far so good. I wish it came with more instructions- such as about the light on it (does it mean it's heating up?) but it seems to do the job!"

Good heater
Date: March 2, 2009
"this is a very nice heater, it sits quietly & does a great job at keeping the water warm.
the con of putting it at the bottom of the tank is that you have to stick your arm all the way thru the water to adjust the temp.
but 1ce you get it the temp you want, it does a great job maintaining it.

Ok but not the greatest
Date: February 11, 2009
"I bought this heater over a month ago, and it was great for the first couple of weeks. But now it does not keep the temperature consistant. The temperature varies now between 8 to 10 degrees with in a day making the fish more Susceptible to diseases."

200 W Heater
Date: January 18, 2009
"I have a new 55 gal Salt Water tank. This heater seems to be keeping the temp OK but the blue pattern on the outside of the tube is flaking off. - anyone else having this problem, don't want to exchange for more problems as I like the design of the heater but I also don't want the fish eating the pattern flakes floating around."

It WAS ok...
Date: January 9, 2008
"I've had the 50 watt for my 10 gallon tank for just over a month and it was keeping it at a perfect 80 and I was really happy... but now it keeps fluctuating the temperature between 12 degrees over the course of a few hours and that is not good for my fish. I'm going to return this one and buy the same model again. I liked it, the one I have just doesn't want to work well right now."

Heater
Date: October 27, 2007
"I have two of the 200 watt heaters in a 125 gal tank. They are great, have never had a problem yet, knock on wood. Keeps it right at 80 degrees even in the michigan winter. Gets my vote."

didn't work out of box
Date: September 24, 2007
"I am setting up a saltwater tank for the first time. All is going well except this heater. I followed the instructions, assumed it was working but discovered today it was cold!!
So I am cycling cold water at the moment until I can return this thing and buy a more reliable product. Glad I don't have fish yet!"

Works for Me
Date: May 6, 2007
"I have a small 50watt heater in a ten gal tank. Hasn't broke yet. It states in the instructions to turn it off when changing the water, maybe this was the previous reviewer's problem."
