I purchased a smaller heater (not hygger) that did not keep consistent heat. It would drop down at night when it got cold. THIS little guy has great suction cups and keeps very consistent heat. Hygger products have made their way into several of my aquarium needs and don’t disappoint. This heater is a great value and an exceptional product. Buy with confidence.

Have this in my 3.5gl tank and it keeps temp perfect. Recently I also purchased this again and put it in my Letpot hydroponic kit and it still is working great for the water for my plants.

This small heater works really well, but just note the accuracy may be off on the control. I noticed the unit is about 2 degrees off, not a huge deal just keep it in mind (your accuracy may be different so don't go by my 2 degree difference).The heater seems to heat up at a decent rate. You won't get controls in other compact heaters similar in size so this unit is fantastic and convenient.I'll update my review if I find any issues with longevity.

This is a nice little heater. The digital readout is brigh and easy to read. It seems to be pretty accurate as it reads the same as the alcohol thermometer that I put in with it. My only complaint is that the readout & temp module is on the wrong end of the power cord. It is much closer to the plug end rather than the aquarium end so that if you want the readout near the aquarium, chances are there won’t be enough cord length to reach an outlet.

Heat timing is terrible!I bought a 2.5 gallon tank and heater from the local aquarium with a heater that was pre-set at 78 degrees. My betta fish like the tank to be about 79-80 degrees so I bought the hygger tank heater because it allows for heat adjustments.Keep in mind, my tank was ALREADY at 78 degrees when I put the hygger heater in. How hard could it be to jack up the heat by ONE degree?? Apparently, very hard.I took out the old heater, put the new hygger heater in, and set the temperature for 79. Unfortunately, the hygger STARTS at 62 degrees and works its way up to the desired temperature. That's crazy!! Why doesn't it automatically start at 78 like every other preset heater??? 19 hours later, and my tank is still only at 78 degrees.Nowhere on the box or in the instructions does it say that the heater starts at 62 degrees or that it takes a full day (maybe more...who knows??!) to get it up to the desired temperature. I thought about leaving the other heater in the tank while I waited for the hygger to finally kick in, but I didn't want the hygger to detect warmer water and stop working (as the directions say it will do), and I didn't want to risk over heating my fish.Overall, just really poor directions and a total lack of communication on how slowly the heater would reach 79 degrees.My poor betta fish is doing fine so far but I feel bad for him having been so stressed.

I have had the heater since August (it’s now March) and the other day the blue light stopped working and the heater started going up in temp, I emailed Hygger and the immediately sent a new heater the service was amazing. Just to note I did have a backup heater which I have for both of my tanks. I have many Hygger products and love them and now I love them even more. you can’t beat good service :)

Small but powerful. If this thing holds up it will be the heater I start buying for all my tanks.

Lo uso en acuario nano para camarones, es muy preciso y eficiente. Tamaño pequeño y muestra en tiempo real la temperatura del tanque con un termómetro digital

TenÃa el modelo de 25w en un acuario plantado de 5 galones. Las primeras 3 semanas funcionó a la perfección manteniendo el agua a 25ºC constantes hasta que hoy note que estaban saliendo burbujas muy pequeñas del caucho de abajo que protege el calentador y al ver la temperatura la habÃa subido a 34ºC y a pesar de que la lectura del display estaba bien, no dejaba de calentar… me parecÃa un producto bonito sobre todo por el tamaño pero creo que no vale la pena arriesgarse y mejor comprar una marca más establecida.
