My wife has been wanting an electric fireplace. I don't like'em. I held off, but our tenth anniversary is coming up, so I ordered one she picked out. OK fine, whatever. Turns out "some assembly" required is not the full story. I'm waiting on our electrician to come and hopefully install it, an electrical outlet has to be moved. It's heavy, I can lift it but I certainly can't hold it up against the wall to secure it.
She usually gets what she wants, I hope she doesn't turn on the heat in summer.
