Does not fit Sun Sun 304B models - pipe is too large
A lot of people are complaining that the 5/8" size is too small and fits their canister's pipes too loosely. And when I received mine, I had the same problem. The heater adapter fit in my pipe so loosely that it simply slipped in and out all by itself. Very loose fit - NOT snug at all. That said, I don't believe it to be the heater the manufacturer's fault. After I got over my frustration, I actually took the time to measure the heater fitting (outside diameter) and I measured the inside diameter of my filter pipe. And guess what? The heater fittings are correct - exactly 5/8" - as specified by vendor. It is the pipe on my filter (Sun Sun 304B) that is incorrect. The internal diameter of the pipes on my SunSun 304B are a little over 6/8" wide. That's why the heater fits the pipes so loosely. Like others, I went to the hardware store and purchased two stainless steel worm hose clamps and used those to secure the connections. But I still worry as I had to really screw them on hard to get a fit that does not leak. It is fine now, but I'm probably going to keep looking for another solution that will make me more confident that it will not fail. Maybe silicon them in and then clamp down on them.After all the extra effort though, I will say this. The heater itself is amazing! I watched it take 125 gallons of water from 19 Celsius to 20 Celsius in 81/2 minutes. It went from 20 - 21 Celsius in another 10 minutes. By the time I woke up the next morning 6 hours later, my 125 Gallon tank was at 27 Celsius. While it was heating the water, I could put my hand in the tank next to the outflow and feel warm water flowing out.In summation, make sure you measure the internal pipe diameter of your canister pipes before buying this unit. I have attached a couple pictures so folks can see what I am talking about. If the internal pipe diameter is 6/8" or greater, you will need to get yourself some hose clamps to ensure a tight fit.

I was happy with this external aquarium heater. It kept the temperature fairly stable in my 125 gallon tank. Yesterday I realized the tank was cold and the heater temp display said HI. So, I shut it off and put in a couple of immersion heaters temporarily. Today, I was hoping that a good cleaning would solve the issue, but it didn't. So I decided to open it. As you can see from the pictures, some water went inside, the insulation around the heating element didn't work well when wet. You can see the burnt/melted plastic parts and corroded power connection. The reason it failed was one of the temp sensors is open circuit. This is meant to work right outside the tank, attached to a water hose. It's natural that there will be water outside the housing, but that water is supposed to stay outside. All they had to do was to make the case water-tight either by using an o-ring around the case opening, or seal the case shut completely. One can get an electric shock with a product like that. They saved a dollar at best, and the product is dangerous because of it. Unless you plan on using it in a dry environment (ha ha) think twice before you buy.

Great heater. I was a little apprehensive to use it since I had not known this brand and the few reviews about boiling a tank but those were simply user error.
This 500w heater keeps my 55 gallon tank within 1 degree and draws exactly 500w when running and only a few watts while monitoring.
As a warning to any new aquarium keeper ALWAYS USE A DEDICATED HEATER CONTROLLER ALONG WITH ANY HEATER! If you cook your fish due to a failed heater, it is your fault for not adding a redundancy shut down option. I suggest the inkbird thermostat heater control for around $35.00. great price for peice of mind.

I did research before I selected this. I read all the reviews and was hoping to receive a flawless product as some people claim faulty ones. I did read the tube size issues and the clamp issues that people reported, so I prepared myself.
I have a Marineland C series canister filter wich come with very thick tubing. The picture of this in line heater showed two sizes for tube connections so I figured one would work. As others have suggested, I purchased a clamp kit with it. I measuerd all my tubing out and connected them with ease and clamped them as shown in my photo. After getting everything ready I nervously got the filter pump started crossing my fingers for no leaks...SUCCESS! Now for the heater itself...I set it to 25 degreess Celsius to give my tropical tank a nice 77 degree Fahrenheit living environment. I also have a floating thermomiter and a digital thermometer that I put in to make sure it is still accurate.
I watched my tubing connectiones carefully for about 30 minutes and then every hour for the rest of my day, each time looking at the temp and comparing. I was very surprised to see that the in tank floating thermometer and new heather were EXACTLY the same, 77 degrees. My digital only went to a 76.3 and 77.4...not once dropping or raising a full degree all day!
I also read that some had water flow issues, but my water flows through this with the same pressure (eyeballing not by technical measurement) very good water current in my 40 gallon tank.
I will give an update after long term use or if an issue arises.
One year update:
Never had a single issue with this running 24/7 (minus water changes) recommended to everyone.
