"Yes, you read that right."

I was worried about the quality but I am thoroughly impressed with this heater! I will definitely be buying another one for my other tanks at bigger one. We received the chiller promptly and put it into use. I emailed the email it says to and told them. This heater warmed it right up and now my Betta and guppies are more active. I waited a little bit to write the review so it could be accurate. The temperature lights up so it's very easy to read.

Finnex HMA-500 Final Thoughts

"I would buy again."

This has the best controller that I have found on the market. 210 gallon ones and one 90 gallon bow front tank. The heater is easy; turn the dial to set temp and plug in. The heater is being used in a 40 gallon breeder. This heater works, but the dial it isn't very accurate. It's only been set up for a month we'll see how well it does in a few months. This product came in the nick of time!

"Great product!"

Very easy to install and the adjustable temperature gauge is pretty accurate. This is a powerful heater that holds temperature very well. We wish the controls were available in Farenheit also to make things a little easier. They shipped us the upgraded version that also heats! Personally for me the housing doesn't bother me. I wouldn't buy any other heater, unless one of these stops working. Also were nice along the whole process.

"The seller was wonderful."

This does a great job at regulating the temp in my 10 gallon. There is no protection from it banging on the glass tank. Pressing and holding the button for 5 seconds changes it from F to C readouts. Temperature is slightly off by running a little warmer. I'm not a big fan of the big glass tubes. I wouldn't buy any other heater, unless one of these stops working. My marina heater takes a few hours.

"No copper lines!"

I will definitely be buying another one for my other tanks at bigger one. The red light means it's off, blue light means the temperature is constant. The suction cups are large, high quality and seem to stick great. The line is there due to regulations in certain countries. I love the heater otherwise, but I'm afraid some water has gotten inside the heater. --The cylinder or rod diameter is bigger. I used to try those other cheap heaters sold on amazon.

"Amazing customer service."

The setting always stayed the same. After several weeks of running the heater. Am a totally sold customer and would recommend them to anybody! I hope these suction cups work very well. You don't have to worry about wide temperature swings with this unit. It's pretty noticeable, but I don't really care. It took me only two tries to get it to the correct temperature.

"Works just as advertised!"

The temperatures are pretty accurate. I noticed my old hygger heater beginning to fail and my wife ordered this one. I left seller feedback yesterday but have yet to hear from the seller. I will definitely be buying another one for my other tanks at bigger one. But my guys don't read them and don't listen! The suction cups are large, high quality and seem to stick great. Or better yet, conceal it to the back corner.

"Well written but vague."

We would consider a replacement and then we would return the defective unit. Once attached to the tank wall I've had no issues with it coming off. This this is amazing and is worth the money. Also were nice along the whole process. I have a few of these and I use them in my 55 gallons tanks and a 29 gallon tank. The heater is super thin and the reflective surface is interesting. So if you set it to 78 degrees, the heater will not kick on until it reads 76.
