  • Easy to keep aquarium regulated
Size: 100W
I love this heater. Easy to read and set It keeps my 37 gallon tank at an even temperature

  • Failed after nine months but company was exceptionally responsive and honorable in replacing it.
Size: 300W
Bought this on February 16th 2022. Installed and set it to 78F. On November 28th the overheat alarm went off that it had heated the water to 94 degrees F. Unplugged it, externally inspected it and saw no problem. Allowed the tank to cool down to 76, plugged it back in (to see if a simple reboot would cure it), set it to 78, and the problem recurred. I didn't see a warranty and so left a poor review. However, the company saw the review and contacted me. After a few communications and a bit of detective work we arrived at what may have been the cause of the problem (a possible manufacturing defect of the controller's circuit board). Although, I saw no formal warranty, JamgoZoo is sending a replacement. Five stars, and more, if possible, for integrity, communications and customer service. I should also mention that at no time did anyone at JamgoZoo request me to change my original review. There was no quid pro quo, they simply wanted to make it right. Last of all, I should mention that before the problem I had checked the accuracy of their thermostat and it was within one degree. A first-class company all around. Buy with confidence. ... show more

  • They work, but do I trust them?
Size: 200W
I ordered three of these in three different sizes - for a 20G long, a 55G, and a 105G hex (100W, 200W, and 300W). They all seem to work, as I've measured the temperature using a temperature probe and they all seem to be +/- 1 degree of what the LED reading displays. However, two of them have randomly overheated the water. As I've been cycling the tanks, I had all three set to 80 degrees, then lowered them to 78 after about a week. However, I few issues: 1. The 300W heater stayed on for a while, even though the temperature was set to 78. The reading on the thermometer read 84 and my separate probe measured 84.6. The display also had the "keep" light on, so I'm not sure if it was actually on or off, but I assumed it was on because of the temperature. I unplugged it and plugged it back in and the temperature eventually came back down to 78. 2. The 200W heater was also set to 78 and, after a water change, the reading went from 77 (because the water I added was a little cooler) all the way up to 82. My separate probe read 83.4 degrees. Again, I unplugged it and plugged it back in and the temperature eventually went down to 78. So, while they seem to be working, I'm highly wary of them. I think I'm going to add a separate temperature sensor with a cutoff because I've added fish now and don't want this to happen again. ... show more

  • Love beefy grid and LED controller
Size: 200W
A Facebook friend told me about this. My Fluval heater is running hot (84F). I ordered this for my 37-community, just in time for the first cool nights below 74F in Florida. Unit looks cool. I like the orange heating tube, separate external controller, dual red LED displays and the grid around the heating tube. The description however lists “100W/200W/300W/500W,” but only a 200-watt version is available currently. 300-watt coming in weeks. It says the heater lasts “at least 1-2 years!” It had better last a lot longer than that. JamgoZoo does NOT sell any other aquarium supplies. There are many models like this available from unknown sources, also with bad English. Many of them cost more. The package is professional. There is a hook included to support the wires. the grid around the heater tube makes the unit look quite substantial. The heater tube is sparkly gray. The safety grid is beefy. The cord is long enough to hide the heater tube across the bottom of my 37-community, behind the Sword plant, but for now I have it in the middle of the back wall. I like the red and blue LEDS, indicating when the heater is ON. I really like the external controller with LEDs; my 1st. To track the high temperature in this tank, I have 2 hard-to-read digital and 2 analogue thermometers. Now I have an easy-to-read controller. I need NOT use the sticky cord hanger that comes with it. ... show more

  • Easy to know the temp at a glance.
Size: 500W
I know this is the best heater for my 130 gallon aquarium. I've had it two weeks, it looks nicer than any other one I've used. It's nice to walk Into a room and and know the water temperature from way across the room at a glance. It keeps the temperature where you set it perfect. My only complaint is the temp read out is about two degrees higher than the actual water temperature, so once you adjust for that it's really not any problem. I highly recommend this product. ... show more

  • Only 4 stars due to the design
Size: 100W
I will only rate this 4 stars due to the fact it's a 1 piece design which I didn't realize. People with a closed top will have to make a HUGE hole to feed it through. It would have been great to have the heater unit unplug from the controller so I could feed it through the back of my canopy and in through the back of my base cabinet. ... show more
