HITOP HP-608 Submersible Aquarium Heater 25W 50W With Thermometer and Extra Sucker Cup (25W)

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!

Arrived on time, and is working well

Great product for the price, I originally bought this for my Betta tank but discovered that it was a bit fiddly to get to the exact temp using the knob on top, I found it seemed to be around 1°c off and also seemed to fluctuate buy a few °c throughout each day, discovering this I decided to move this heater over to my cold water tank to maintain the temperature instead of it heating the tank, it does a great job at this and is keeps my goldfish at a stable temperature. You get what you pay for, not great, but not bad either.

I have a small aquarium and needed a small heater to keep the few fish happy over the winter months. It definitely heats the water but I think the temperature control is not the greatest, I need it to be at 20 but the water feels a lot warmer than that, I do need to get a reliable thermometer just to check the water isn't actually getting to hot but for now during this really cold winter the fish are happy and that's the most important thing.The heater is so easy to set up and install and the suction cups are good quality as they are keeping the heater securely in place, as already motioned the only thing I have any doubt over is if the temperature control works correctly at the liwest setting. I have no reason not to recommend this heater as it is so easy to use and would heat a tank upto 30 gallons easily

I needed a heater for a 30l tank that is discreet, works well, looks good, and that wasn't going to break the bank and this one did just that. It was an instant setup - and I have been using it for a few months now. It keeps the tank nice and warm and my fish and shrimp are all happy. It is very important to keep the entire thing submerged in water.

Very simple device that does the job perfectly.

Purchased for heating water to germinate lotus seeds and it's perfect so far. After just 48 hours the plants had started to finally growing roots. It's a great price, I hope it continues working.

The heater light is constantly on or off, and the temperature does not reach the desired level that it’s been set to.
