I love this type of heater for my aquariums. It is very easy to set up, and the digital readout makes it so much easier to make sure it is maintaining the correct temperature in the aquarium. It is difficult to find a heater that fits into small tanks so well without it being unsightly. I have installed this into a 10-gallon aquarium, and it has been very consistent at keeping the temperature within range even in the room that particular aquarium is in, as the room temperature fluctuates greatly from daytime to nighttime. I like that it has safety features for when the tank is out of water. I have burned up a couple of heaters because I have forgotten to unplug the heater when doing water changes. Looks sleek and far more aesthetic than traditional heaters.

The heater and thermometer were simple to install and easy to set up with a great design for attaching to the aquarium.  The instructions were poorly written, yet rather comical due to the translation I’m sure, but could easily figure them out.  The listed price is great so overall it’s proven to be a quality purchase and the fish are thriving.

This is a small, 50 watt heater- literally 5" long, but it is good for keeping a 10 gallon tank at a set temperature.It heated my 10 gallon tank in about 40 minutes to 77°F, with my room temperature at 69°F. Once it reached the set temperature, it has consistently maintained the water temperature to within +-1 degree of the set temperature for at least several days.Setting the target temperature was super easy, and the heater stays in-place under with water with the included suction cups with no problems.I am not sure I'd recommend this for any tank larger than 10 gallons, but if you have a 2½, 5 or 10 gallon tank, this should work fine. It's accurate and proven able to keep close to the set desired temperature. Only time will tell how long this heater will last, but it seems to be constructed well, and the temperature setpoint is displayed on an easy-to-read LED panel.Price is decent too, so I recommend this heater for anyone needing to heat a 10 gallon or smaller tank.

This is a well made and highly functional heater for your fish tank.Easy to use, easy to move, and easy to put bag, the digital thermometer makes it exponentially easy to use.Able to keep our large tank warm and happy for the fish, it's great out of the box.

This is a nice heater. I love the digital display telling me what the current temp is at (and it flashes to what temp you're setting it to when you first plug it in). It defaults to 77 degrees which is pretty standard for a tropical freshwater tank.I wish the cord were a little thinner, but since most cords are super thick on aquarium heaters I'm guessing there's a reason they need to be.The suction cups it comes with are easy to clamp onto the heater, and stay put very well on the side of the tank.

I have mixed feelings about this heater. On one hand, it works but you have to be very careful about the temperature you set it at because it will fluctuate by almost 2 degrees which could be detrimental to your fish friends. On the other hand, for the price point it is the perfect size for a small tank and can stay at the back with the suction cups which work very well at holding it in place. It heats the water fairly quickly but has a bit of trouble keeping it really super consistent. I don't blame the heater entirely, the ambient temperature in my house is on the cooler side so that could be why it struggles. Overall, it is a good value for the money just set the temp at a moderate temp and don't go too aggressive with it.

Apparently, I’ve accidentally started collecting nano aquariums like some people collect coffee mugs—except mine require heaters, water changes, and occasional existential crises over fish personalities. Since most of these tiny tanks didn’t come with heaters, I needed a reliable one, and so far, this little guy is doing its job well.The LED digital display is a nice touch, letting me obsessively check the temperature like the overprotective fish parent I am. Overheating and off-water protection? Great for peace of mind in case I ever get distracted (again) by setting up yet another tank.
