    • Works perfectly!
Pattern Name: 25W
This is a great little heater. I have a 2.5 gallon tank for my betta and I had a hard time getting the water to stay above 74'. When I placed the heater in the tank the light turned red showing it was heating up and within about 10 min the light turned green. I use a glass aquarium thermometer in the tank and and it showed the water was a perfect 78'. Every now and then it'll turn red and then green after a few minutes showing me its working amazing to keep my betta at the perfect temp. I highly recommend this heater! ... show more

    • Very big
Pattern Name: 150W
First of all this thing is big. It is about three times bigger then the Tetra heaters with equivalent wattage. The dial is about 3 to 4 degrees off from the actual temp. What is weird is that the instruction manual even explains this. The digital thermometer that comes with it is also not accurate. I tested it with an ice bath and found that it runs about 1.5 degrees hotter. I bought this heater because I needed a cheap heater quick. I plan on buying a better heater latter and keep this only as a backup. ... show more

    • Good once the temp is set
Pattern Name: 200W
I've been using this 200w heater in my 45 gallon reef tank for seven months. It heats the water well, and I'm happy with it. You do need to pay attention when you first install it to set the temp. The numbers on the dial aren't precise, so I suggest using this with an InkBird temp controller. I set the temp at what looked like 78, but it was warmer, so my InkBird cut the power. I had to make very small adjustments and then wait to see what temp the heater would maintain. After a few days, I had it dialed in to 78, and it's been perfect since then. As with any heater, you could overtemp or chill your tank if you don't pay attention while finding the correct setpoint. I highly recommend using this heater with an InkBird ITC-308S controller. ... show more

    • Don't let my 4 Stars Rule This Heater Out From Your Purchase of It.
Pattern Name: 100W
The 4 Stars was given for several reasons, neither of them would rule out purchase of this item again. TEMPERATURE CONTROL: Temperature is about 2 degrees warmer than the digital probe reads. NOT too bad. That said the 100 watt & 150 watt are priced the same. The carton had both shown wattage's shown, AND had a blank or "empty Check-Box" to ID the wattage. I ordered a 100 watt and I think I received a 150 Watt. Even when new, my previous 100 watt heater, seemed to heat the water slower than THIS on. (OK for me because I was slightly Under-Powered with a 100 watt in my 29 gal. tall tank). SUCTION POWER: I found through the years of replacing heaters in an existing/and balanced tanks, ALL heaters with suction cups have never held very long. A NEW tank they might work better. (I am only guessing) ACCURACY: I covered that at the top. Only 2 degrees warmer on mine, than what the dial reads. Not real far off. JUST A HINT IN GENERAL: I usually set my new heaters just only a little higher the actual water temperature, AND THEN, then keep a close eye on your temperature as it raises. You don't want to cook your fish, IF for any reason your heater when being assembled, had a 'manufacturing problem'. ... show more

    • It works, wish it was easier to read
Pattern Name: 300W
I bought this to replace mine that went out and I needed it in a hurry so I didn’t do that much research. I feel like it works just fine, but I wish it was easier to read where the max water line should be and that there was an indicator light that it was on. That’s kind of something that I feel is missing from this but other than that it works. I will point out that the thermometer that comes with it is off by about 2 degrees compared to my other ones. I was concerned the temp was too high as it was reading 82.5 when I had it set to 79. That can be a big difference if you are keeping sensitive fish so having a thermometer that actually tells the correct temp is pretty important. ... show more
