Thank you for viewing! I have kept this item in storage, unused. I opened the package to test the product's functionality, charged it once, and the light works without issue. 【Product Description】 This is a smartphone camera lens equipped with a 0.4x-0.6x wide-angle lens, a 15x macro lens, and 10 LED lights. The LED lights have 3 levels of brightness adjustment, which is especially convenient when taking close-up shots using the macro lens. It's a versatile lens adapter that can be used in various situations. It can be attached to most models, such as i-Phones and Xperia, with a single touch.
