It was advertised to make $100/season
It was advertised to make $100/season. (3 months, maybe 4) So you would expect to make $25-$35/month. I've had it on non-stop for 13 days and made $3.74. Also, as a heater, It did not get as warm as some of my other space heaters. I've never seen it get over 72 degrees. I'm not happy with this purchase at all.
