We bought this for my son’s bedroom. He isn’t well and thought the ambiance and heat would be perfect...and it is!! The 2 heat settings are ideal. We keep it on without the heat more often because it is very calming! Installation was pretty simple. If you can hang a heavy picture with plugs you can do this.  Lay the rocks down along the bottom laying flat then put the glass cover on...the rocks fall into place.  For an added touch I downloaded an app that crackles like a fire...just for fun. Love that we have a “fireplace” in his room for us all to enjoy!
