Actually 4 stars because the anti fogging is just so so …not 100% effective. That photo was taken with anti fog feature ON, bathroom fan on. Also photo was taken AFTER my shower!!!!   You also have to pay someone (unless you are an electrician to put in a box / electrical behind the mirror  so that you can just flip the bathroom switch. The mirror is also heavy enough where 2 people are needed for installation. Also this mirror DOES NOT give enough light to be the only light in the bathroom. You MUST have other sources of lighting. We have 3 can lights and bathroom i, but it’s a big bathroom.
Otherwise it’s a beautiful mirror and I would have bought one more for a different bathroom but company didn’t have the size I wanted.
