"Bought the 300W one."

Personally for me the housing doesn't bother me. I used to try those other cheap heaters sold on amazon. Sometimes it gets outside of it's ability to cool but only within a few degrees. There is a misconception on the internet that the heater isn't fully submersible. Easy enough to let it run all the time. I noticed my old hygger heater beginning to fail and my wife ordered this one. This heater warmed it right up and now my Betta and guppies are more active.

"Same suckers for years!"

Keeps the water consistent and it's easy to adjust! Takes a little while to drop the temps if it is hot in the garage. Sometimes you may have to tinker around with the dial.

Once I opened the box i noticed the quality of the construction.

"This heater works great."

The red light means it's off, blue light means the temperature is constant. It does blend well in some setups and may look bulky in others. I have had to turn the dial to about 78-79 for the tank to stay around 76 degrees. This does a great job at regulating the temp in my 10 gallon. This heater works, but the dial it isn't very accurate. My heater is fully submerged underwater and works perfectly fine. The bonus digital thermometer it came with has been super helpful, and is accurate.

Sometimes you may have to tinker around with the dial. There is a misconception on the internet that the heater isn't fully submersible. I got the 200W variant for my 54 gallon corner tank that's housing goldfish. Or better yet, conceal it to the back corner. This this is amazing and is worth the money. I contacted the manufacturer and they sent me a new unit in less than a week! Or better yet, conceal it to the back corner.
