I had an existing old plastic box shatter and needed a replacement that could fit within the existing hole in the ceiling. This box was excellent quality, the screws were a little difficult to drill into the joist but the end result was excellent. No trimming of the existing hole was necessary.

I wanted to install a ceiling fan but the original box was not rated for it. After removing the original one, which took some coaxing, I installed the new one with minimal fuss and without having to make any additional cuts on the drywall. Installing the fan afterwards was a breeze, and it stays firm and secure. Excellent product, solid build (thick plastic supported by a metal structure) and very easy to install - you just need to drive the 3 screws that come with it onto the side of the joist. The screws even come positioned so that you can screw them at an angle that allows the use of any power screwdriver.
