Installed mine Nov. 2024 by professional installer. Excellent little insert-generates huge amounts of heat. Would definitely buy another one. (have Drolet stove in basement as well). Although, we are are very happy with the product certain quality issues have to be addressed (thus 4 stars)- hope that my submission will help company addressing some quality control issues. 1. Set of assembly bolts for the finishing frame were not in the factory package (fortunately I had some at home, so my installer was able to finish installation - with some extra black paint.) 2. Blower fan is not properly (designed or assembled) - thermostat does not engage at all - due to extra large gap. My installer called tech support but could not find a solution, so I had to rewire the switch, so it could be turned on/off manually, abandoning sensor functionality altogether. (many reviewers are pointing the same problem). 3. Air intake lever does not have any indicators on how wide is open - that should be improved.
