5.0 out of 5 stars Neat
By Jann Ford on 13 April 2019
These heaters appear to be working very well in my Betta tanks. They look good and the built-in thermometer is great.
My only concern is the display lights are too bright for night time.
(I'm pretty sure you can't turn the display off without turning the heater off)
