This was purchase last holidays but I finally installed it this past November, after completing some reno work in our home. Looks great, easy to install. I opted to for the build in look due to this model having the heat vents in the front.  Cant say it warms much, but my cats seem to really enjoy it when that feature is on. My only concern is that is has recently started making a humming, buzzing sound when on. It is not loud but noticeable enough to start bothering you after a while. Not sure what it is, & Im hoping its something minor. Other than that it looks beautiful surrounded in stone.  Im hoping we get many years out of it, I will be disappointed if this buzzing noise leads to other issues.
