"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!

"There was only~0."

It is a bonus that the heater is titanium. No biggie, but annoying nonetheless. I have a 10gallon tank that was at 72 degrees. I had a thermometer on opposite side of tank and the heater was dead on true. The heater protector was very heavy plastic and slim lined which is great. They shipped us the upgraded version that also heats! I like the fact that it comes with a digital thermometer.

YukiHalu Final Thoughts

"They contacted me."

The suction cups are large, high quality and seem to stick great. It is a bonus that the heater is titanium. Per my thermometers, they are all staying constant. Would be great to be able to tune that to. I left seller feedback yesterday but have yet to hear from the seller. The heater protector was very heavy plastic and slim lined which is great. It does blend well in some setups and may look bulky in others.

"Just perfect for my 1."

I'm in the process of setting up for tanks. This little heater is perfect; this is our third purchase of the same heater. This heater warmed it right up and now my Betta and guppies are more active. I like to keep it at 72 and from my thermometer it is reading at exactly 72. Product was received fast, works excellent! Those turned out to be a hit and miss. It would stick out of my 30 g wide tank if I were to put it vertical.

Uniclife Final Thoughts

"This heater works great."

This does a great job at regulating the temp in my 10 gallon. I adjusted the set temperature a little lower to be more in the range I wanted. --The heater itself is a bit shorter if your tank is a short one. No biggie, but annoying nonetheless. The setting always stayed the same. This is a great heater that is very easy to set up and program. There is no protection from it banging on the glass tank.

Takes a little while to drop the temps if it is hot in the garage. It comes with a hanging kit and can be secured on the edge of the tank. The line is there due to regulations in certain countries.

"Until the next time."

I wouldn't buy any other heater, unless one of these stops working. Easy enough to let it run all the time. I'm not a big fan of the big glass tubes. They promptly fixed the issue without any delays or drama. It took me a few days slowly turning the dial up to finally get it where I wanted. I noticed my old hygger heater beginning to fail and my wife ordered this one. Sometimes it gets outside of it's ability to cool but only within a few degrees.

"The seller was wonderful."

The heater is super thin and the reflective surface is interesting. The design is sleek and modern looking. Ick for instance detaches from fish at 86 degrees and dies at 89. 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. Just be careful and keep an eye on your temp settings when you have kids over! So far I like it setup was super easy.
