"So far it seems great!"

I went ahead and went with the the larger 300W for my 45 gallon. Keeps the water consistent and it's easy to adjust! There is no protection from it banging on the glass tank. I have a few of these and I use them in my 55 gallons tanks and a 29 gallon tank. I would definitely recommend this product. This is a powerful heater that holds temperature very well. So when I first received it it didn't work and I was very disappointed.

AquaClear 11182 Final Thoughts

"That wasn't a good sign."

Those turned out to be a hit and miss. The heater protector was very heavy plastic and slim lined which is great. The heater is super thin and the reflective surface is interesting. The temperature lights up so it's very easy to read. You don't have to worry about wide temperature swings with this unit. Temperature is slightly off by running a little warmer. I am very happy with this purchase.

Fluval A767 Final Thoughts

"I like this heater."

I noticed my old hygger heater beginning to fail and my wife ordered this one. The heater is super thin and the reflective surface is interesting. After several weeks of running the heater. Come on Fluval, expect better from you. Takes a little while to drop the temps if it is hot in the garage. We wish the controls were available in Farenheit also to make things a little easier. The heater is being used in a 40 gallon breeder.

SeaELF Final Thoughts

"I like this heater."

Now, both points are clear on the package instructions. We received the chiller promptly and put it into use. Well I bought a second one took me only one trying to get the right temperature. The cover over the heating tubes is great, the turtles claws can't damage the tube. I use a 50 for a 5 gal and a 10 gal tank. My marina heater takes a few hours. I have a few of these and I use them in my 55 gallons tanks and a 29 gallon tank.

"Great heater."

It took me only two tries to get it to the correct temperature. It does blend well in some setups and may look bulky in others. The red light means it's off, blue light means the temperature is constant. We would consider a replacement and then we would return the defective unit. This is only day one though, so I shall keep an eye one it. Well worth the money the first one I bought still works great. So far I like it setup was super easy.

I would definitely recommend this product. And I get to keep the first one I bought! It would stick out of my 30 g wide tank if I were to put it vertical. What more could you ask for great job Hygger Duncan. I waited a little bit to write the review so it could be accurate. Will update my review if any changes occur. I recieved this product without the instructions or the added thermometer.

"Pricing was good."

I appreciate the exterior temp readout and control module. There is no protection from it banging on the glass tank. This heater is NOT fully submersible. I wouldn't buy any other heater, unless one of these stops working. Now, both points are clear on the package instructions. Maintains it well except when the weather is already warm then it over heats it. It would stick out of my 30 g wide tank if I were to put it vertical.

"Bought the 300W one."

Per my thermometers, they are all staying constant. I will be ordering more of these in the future. My marina heater takes a few hours. All seem to vary between 1-2 degrees of each other which doesn't concern me much. The suction cups are large, high quality and seem to stick great. Once attached to the tank wall I've had no issues with it coming off. This is only day one though, so I shall keep an eye one it.

"Highly recommended."

So when I first received it it didn't work and I was very disappointed. The temperature gauge is fairly accurate in my 55 gallon tank. I will definitely be buying another one for my other tanks at bigger one. I have it set to 81F to get a 77F water temp. I have had to turn the dial to about 78-79 for the tank to stay around 76 degrees. The heater is being used in a 40 gallon breeder. The bonus digital thermometer it came with has been super helpful, and is accurate.
