"I couldn’t be happier with this aquarium heater! It’s reliable, efficient, and maintains a consistent temperature, which is so important for the well-being of my fish. The adjustable thermostat is easy to use, allowing me to fine-tune the temperature to exactly what my tank needs. I’ve been using it for a few months now, and it has kept the water temperature perfectly stable, even during colder days.What really impressed me was how quickly it brought the tank to the desired temperature after setup. The build quality feels solid, and the indicator light is a nice touch, letting me know when it's actively heating. The compact design fits seamlessly into my tank without being too obtrusive.Overall, this heater has made tank maintenance much easier, and my fish are thriving in their warm, comfortable environment. Highly recommended for anyone looking for a reliable and affordable aquarium heater!"

Works well, heats water effectively and the external display is very handy for keeping an eye on the tank temperature.

Seems to be working fine

I purchased this to replace a a cheaper one that failed within a week. SO far so good. I have installed it in my tank. Really easy set up and instructions, the external themometer and control is great. My only complaint, and as mentioned in other reviews is that the display is blurred because of the frosted plastic that covers it. I don't think this can be removed without the display getting damamged. you can make it out but it's not very easy. The photo does make it look worse than it is though.

Good product

Bought this heater for my 280l synodontis tank and I have absolutely no problems with it. The cage the heater is in reduces any burn risk to my synos as they like to rest on the heater and often clean any debris off of them.The temperature display works well and also helps me ensure I keep the water the same temp at water changes (30% changes, keeping heater submerged as it is positioned lower than the amount I remove).Traditional heaters always scare me as I’ve heard horror stories about them cracking and zapping all the fish in the tank etc. but this heater gives me peace of mind. I will be buying more for when i set up my next 2 tropical tanks which will be soon.

I like these heater ,I have two in different tanks ,they work perfectly.
