Customers are saying

Customers are delighted by the iPhone XS Max Smart Battery Case's extended battery life and wireless charging capabilities. Many appreciate its protective qualities and the overall build quality, noting a positive user experience and ease of use. However, some users find the case to be somewhat bulky and heavy, and the price point is a common concern. The size increase is also mentioned as a factor affecting the user experience.
