### ⭐⭐⭐⭐ 







  
  
    Does what its supposed to do.
  

*by L***. on Reviewed in the United States on February 19, 2023*

Did a good job of reflecting light back down onto the kitchen table below.  Table top was previously dimly lit.  Half of the light from the upward-facing light-fixture bulbs was illuminating the ceiling.

### ⭐⭐⭐⭐⭐ 







  
  
    Replaced Bulky Heavy Glass Globe
  

*by P***. on Reviewed in the United States on March 3, 2023*

A bit pricy for a piece of round plastic, but I am happy with the results. It replaced a heavy, bulky glass globe that was a nightmare to remove in order to change the bulbs. If it lasts, I will upgrade the value for money to 5 stars.

### ⭐⭐⭐⭐⭐ 







  
  
    Perfect replacement on my ceiling fan
  

*by P***S on Reviewed in the United States on January 22, 2023*

The shade I had was broken. I needed a shade that had a hole in the center for the pull chain. Not as easy to find as you would think. I found a glass shade but it was so heavy it was pulling the lighting mount off the fan. I found this diffuser which works perfectly. The  center hole was 3/8 but I drilled the hole to 1/2 inch. The disc is heavy plastic and comes lined with paper on both sides. I drilled the hole and peeled the paper. No damage to the the disc with drilling.
