Review: Great product! - Works like a charm. I was renovating my bathroom and found that they had not used a box for the vanity light when they built the house. Unfortunately the studs were not close enough so I opted for one of these and glad I did. With a w.25 hole saw, I had the new light done in about an hour (assembly included). I WOULD definately purchase these again!
Review: Perfect installation with the included stencil. - Nice size box for ceiling installation. Biggest convenient plus was the enclosed stencil for the electrical box. Cut out exactly to the stencil was a perfect fit.
