## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great to cover an unused ceiling box
*by B***E on October 18, 2025*

We refit the lights in our camp bathroom. This looks fine in spite of the ceiling being light wood. Installation was a snap

### ⭐⭐⭐⭐⭐ Perfect Product
*by J***T on January 27, 2026*

Easy to install

### ⭐⭐⭐⭐ Worked very well with minor modification
*by R***D on September 9, 2025*

Good product and got the job done with just a little modification. This was to cover an old removed smoke detector but the electrical box was a standard duplex rather than an octagon. I wished they could've just made their spanner/bridge a bit more "universal" but since it was plastic, I used a hobby rotary tool and just ground away a tiny bit on one of the screw slots and then it worked perfectly. The cover popped right on and could be spun back off (for painting). Nice texture, clean "no screw head" look.
