## Customer Reviews

### ⭐⭐⭐⭐⭐ great value and quality
*by B***N on October 18, 2024*

it works good , as advertised, 100% happy and recommend this seller

### ⭐⭐⭐⭐⭐ Worked perfectly
*by T***L on August 30, 2022*

This was the exact fix my projector needed.😊

### ⭐⭐⭐⭐ Decent
*by S***K on March 29, 2021*

Used this to fix a Nelsonic Zelda watch with a bad polarization layer. (Didn't even realize they could go bad). It worked well enough - it darkened the screen just a hair, but the LCD cells are now dark and visible. The film was shipped in a flat, rigid sleeve, but still had a prominent warp to it, and the warp is still visible on the watch face. Giving this 4 stars because it did technically work, but dinged it one because now I have to spend more money on this repair trying to find another sheet that isn't warped.
