## Customer Reviews

### ⭐⭐⭐⭐⭐ So far, No issues!
*by I***W on August 3, 2025*

All tools I needed were included. Plenty of online tutorials that guide you through it.

### ⭐⭐⭐⭐ Used for Samsung Galaxy S22 Ultra
*by Q***G on February 10, 2025*

Would give 5 stars but these only last for a year to 1.5 years before they burn out. But for the cost and size is a great deal.Its good for about 1.0 to 1.5 charges for full day use (photos/videos/ calling) etc.

### ⭐ No es la misma
*by Y***Z on September 1, 2025*

Mal está batería no sirve para redmi k 40 es mucho más grande y además no viene con una cinta conectora k necesita
