What Aqueon Pro Heater owners say

“An Aqueon Pro heater has a lifetime warranty, and that's what I have in both my tanks.”
— Bettamom on Reddit
“Now I just trust the internal thermometer on the aqueon pro heaters and use a digital one as a backup.”
— DSouza31 on Reddit
“Yeah, the latest Aqueon Pro heater model has just sucked. The older one (blue dial) worked really well, so it's really disappointing how they just tanked the quality with the new one (clear dial).”
