Highlighted Reviews

"Lil' Green has a tank that was too cold this winter. She enjoys a toasty 78F weather now even if it's 23F outside! Great heater that meets her needs."

— Lilly

"I didn’t read the reviews until after i bought it, the light just keeps blinking."

Bottom Line

This heather works OK, it is affordable but won't be a long term heater and would recommend others looking at this heater to get a higher end brand even if it costs more initially, to save the time and money of buying another heater in the future. In most cases buyers did not want to purchase again or recommend it to other.
