Great Heater
I got this heater to replace one that I had for several years in a 75 gallon freshwater tank. I received it quickly and it works as described. It installed quickly and easily. The suction cups on the back seem like they'll hold up pretty well. I like that you can control the settings without reaching inside the aquarium and that it shows the water temperature as well. I've had this for a couple of days and so far it is working well. I haven't noticed any issues. I will come back and update this if I do within the next month or so. The only thing that would make this better would be to include some sort of holder that could attach to the outside of the aquarium for the controller. That's just my suggestion and not enough to take a star off for.

An aquarium heater that delivers piece of mind.
This heater is perfect for our 55 gallon aquarium. You just set the temp and forget about it. It does all the work itself. Great function! The black blends right in with the aquarium decor so it’s not that noticeable. Very easy to set up. Anything that makes my life easy is a great value!

Perfect for larger tanks.
Works great for 125 gallon tank. Love the thermostat on it. Not super long but long enough to spread out the heat. Seems to be a lot sturdier than other heaters. LOVE IT

Works Well!
After trying a number of heaters and struggling to keep a steady water temperature I am so glad I tried this heater! The fluctuating water temp was taking over my life. I couldn't relax about it. I live in northern Wisconsin and it gets cold up here. This heater has preformed great so far. It was -6 last night and we do turn the heat down in the evenings. It keeps the temp steady. I love it!

Good quality, easy to use
So far so good, seems like very good quality. Very easy to use , and the temperature indicator is on the end near where you plug it in so it is not seen. Can keep under the tank. Overall quality heater.

Awesome buy!
This is a necessity for fish tanks. It's so easy to use, it's digital so you don't have to guess with the stickers on the glass, I love how long the plug is so I'm able to hide it behind the tank, this heats up my tank so quickly, and it's been used for 2 years now- I bought another tank and ended up buying this item to use for that tank too. Great buy!

Superb customer service; excellent product
Purchased a total of 4 of these. Had a problem with 2 and contacted the company--a year later but within their 2 year warranty. Didn't really expect to get helped after so much time. The 2 malfunctioning heaters would come up to temp and then start blinking an HH error code. The company was excellent to work with and was very professional and helpful. They are sending out 2 replacement heaters as I write. The other 2 heaters have been working great and I would definitely buy again with such superb customer service.

Stopped working after just over a month
I purchased this HiTauing 300W aquarium heater as a Christmas present, and as of today, it has completely stopped working. For a product critical to maintaining a stable, safe environment for fish, this kind of early failure is extremely disappointing. Initially, the heater worked as advertised. The LED digital display was easy to read, the setup was simple, and it heated the tank appropriately. However, after about 5–6 weeks of normal use, the unit no longer heats. The display comes on, but the water temperature drops, and the heater does not engage. This is especially concerning, given that the product advertises “5 safety protections” and is marketed as reliable for aquariums. A heater failing this quickly puts fish at serious risk, and I had to scramble to replace it to avoid temperature shock. For something as essential as an aquarium heater, longevity and reliability matter more than features, and this unit did not meet those standards. Based on my experience, I cannot recommend this heater and will be switching to a more established brand.

The heater works very well (plus 2 years) at keeping the temperature at the desired setting. Easy to setup and fish are happy.

This is the best heater for my aquarium that I have ever had. I've had all the other big name brands, but this beats them hands down. The ability to control the temperature from the external control box saves the messy job of having to dig into the tank all the time to adjust the temperature. This 500W heater easily copes with my 80 gallon tank & maintains the temperature within 0.3 deg C of the set temperature. The temperature differential of 0.3 deg C means the water temperature remains very stable, unlike other heaters that allow sometimes up to 2 deg C change before activating. Quality of construction seems excellent & if it's reliable over time, it will be an absolute bargain. Hugely recommended.

Die Aquarium Heizung, die ich kürzlich gekauft habe, hat sich als äußerst zuverlässig und effektiv erwiesen. Die Leistung der Aquarium Heizung ist beeindruckend. Sie hält das Wasser in meinem Aquarium konstant auf der gewünschten Temperatur, was für das Wohlbefinden meiner Fische und Pflanzen entscheidend ist. Die Bedienung der Aquarium Heizung ist einfach und unkompliziert. Ich konnte sie problemlos einstellen und sie arbeitet zuverlässig, ohne dass ich ständig nachjustieren muss. Die Qualität der Aquarium Heizung ist hochwertig. Sie ist gut verarbeitet und robust, was mir das Vertrauen gibt, dass sie lange halten wird. Die Sicherheitsfunktionen der Aquarium Heizung sind ebenfalls beeindruckend. Sie verfügt über einen Überhitzungsschutz und eine automatische Abschaltung, falls das Wasser zu heiß wird, was mir ein beruhigendes Gefühl gibt. Insgesamt bin ich mit meiner Aquarium Heizung sehr zufrieden. Sie erfüllt alle meine Erwartungen an Leistung, Bedienung und Qualität. Ich kann sie definitiv weiterempfehlen.

I have 4 of these heaters (two 200 watt, one 300 watt and a 500 watt) now and so far they work very well. I can’t vouch for the accuracy of the heat, because I use INKBIRD controllers to manage the temperature. But I can say they are a nice size, and seem extremely well built. The suction cups are the best I’ve seen on any heater or other pieces of aquarium equipment. They heat much faster than the previous heaters I was using. The cord length is perfect if you power outlet is a ways away from your aquarium. And the power cord is a heavy gauge wire, unlike a lot of heaters. I’ve only had them running for a couple of weeks, so I can’t say how long they last. But I will update my review if I have any issues or if one of them dies. I’ll likely be buying a couple more 300 watt heaters as well.
