### ⭐⭐⭐⭐ Works as advertised
*by M***R on January 22, 2024*

Easy to apply and set up as described, but had to translate the details on the back into english from chinese, which is not in the picture. Easy to do though, just take a picture with your iPhone of Android and then highlight the text in the photo and translate to english.
