05/12/21: Update...Seller reimbursed me $18. to purchase another digital control panel. These panels are extremely sensitive and should be strategically placed out of the way. All is working well again!04/25/21: Update...Back light on digital display does not work. I have no idea if it_ on a timer, what temperature it_ at or if it_ on the Off/On position? Emailed company today concerned with warranty and how we can avoid having this happen again :(01/11/21: Love it, love i, love it!Nice dry heat, nothing like at all like propane at all which makes the air wet and gets cold when turned off. I travel in a van in cold temperatures and should have done this yrs ago. It was difficult for me to install and cut holes for the exhaust so I had a mechanic do it. Definitely worth it over propane heat!!
