  • Great Little Heater with one flaw
Size: 50 Watts
This is a great little heater because it doesn’t take up a lot of space, and I love the external temperature control. Very simple to adjust the temperature as opposed to having to put your hands in the aquarium or read a tiny indicator on the heater knob. However, I can’t give it five stars for one flaw. The manufacture found it necessary to label the heater in large letters with Mini Heater. Really? I guess I would’ve known it was a heater if it wasn’t labeled. I set this tank up as a breeder tank, so I really don’t care for anyone who’s setting up a nice decorative aquarium, having a piece of equipment labeled in large letters is unsightly It’s just unnecessary. Previously is was labeled with the manufacturer name, which is a little better. ... show more

  • Excellent warranty support
Size: 50 Watts
The good: great thermometer that works pretty accurately as far as I can tell, and the heater did an excellent job maintaining a steady temperature in the tank. Small and unobtrusive, strong suction cup. The bad: died afer 4 months. My fish were fine, but they're fairly robust. The redemption: reached out to YukiHalu seller account about the defect and received a new heater in a couple days. Outstanding warranty support! ... show more

  • accurate temporature reading
Size: 100 Watts

  • Perfect little heater for my 5 Gallon tank
Size: 50 Watts
This heater is a great little heater. It is easy to use and small enough to hide away. I wish the cord was a little longer.

  • Great "micro" heater...
Size: 25 Watts
If you're OK with your small aquarium water temperature between 76 - 80 degrees Fahrenheit, this is a great buy! It's automatically set to 78 degrees and not customizable, which was the only detractor for me. Keep in mind, submersible heaters typically keep the water within 2 degrees of the setting, so as long as that temperature range is good for your aquarium, it's definitely worth it! ... show more
