I have only had the fireplace insert for a little over a week, but so far it's been great.  It fit my firebox opening perfectly, thanks to accurate dimensions.  There are multiple flame settings and all look very realistic.  The heat pumps out well (two different settings).  And it was a breeze to install.



Cons: We had to fiddle with the remote battery a couple times to get it to work, but haven't had any problems since
