We've been happy with this and are coming up on our one year with it.  The shelves are thick and the fireplace is sturdy one you get it into place.  It's very heavy so it's easiest to move it by taking off the side shelves, which is very easy.  I don't think it's a tip risk due to the weight which is nice.  The TV we have is 75" for scale.  The fireplace doesn't put off a ton of heat, but has nice temperature and time controls.  It just recently started smelling when we use it, but not all the time.    I would recommend this.
