  • Great heaters!
Size: 10.4in-200w
I have used these heaters for years and never ran any issues while using them. I used 50w, 100w, and 200w and they all work great. I bought 2 of the 200 watts one because my fluval one wasn't keeping up the temperature and after putting both in the tank, it managed to raise the temperature as needed. Highly recommend them! ... show more

  • Very good aquarium heater
Size: 10.4in-200w
Works amazingly, even for a larger than rated tank! I've had mine for around 1.5 years and it's still going strong. Amazing durability.

  • Works very well
Size: 10.4in-200w
I've only had the heater for a few days but it is keeping the temperature at a steady temp in my 30 gallon tank. The temperatures on the heater are not accurate but it does help me to know which direction to turn the knob and it is only off by about 4 degrees. I'm very pleased with it so far.

  • Works great
Size: 10.4in-200w
I’m giving this fish tank heater 4 stars because it works really well in my 45‑gallon tank. It heats the water evenly and keeps the temperature nice and warm without any issues. It also looks good in the tank and doesn’t take up much space, which I appreciate. Setup was simple and quick, and it’s been easy to use ever since. So far, it’s been reliable and does exactly what it’s supposed to do. Overall, a solid heater that performs well and blends in nicely. Makes no sound and is safe ... show more

  • Held up well over time
Size: 10.4in-200w
Had for a while now and has always kept my tank at the temp I want it at. It seems very durable and is not hot to the touch for safety of fish. It is pretty compact and was easy to install. It automatically turns on and off when needed which is very nice.

I’m really impressed with this HITOP adjustable aquarium heater. I’m using the 200W model for my 100L tank, and it works perfectly.

  • Don't bet your fish's life on it! Buy a better product. This one sucks!
Size: 10.4in-200w
I know that I don't follow other warnings. Sometimes when I read what other people write about there experience was with products. But I'm telling you now, don't do it! This product if you love your fish! This heater only lasted 2 months and then stopped. I almost lost my beloved fish, George:( But thank goodness I caught it in time and saved him. So once again if you want to risk it go ahead but I'm telling you it's not worth it. ... show more
