Slim, fits well and easy to install. So beautiful and eye-catching.

Lasts noticeably longer than two samsung factory batteries. More capacity at a lower price. Honestly, it's about the same as the stock battery.

No tight fit, now it needs a gentle push before it wedges into the compartment. Also, the pins on the bottom of the lightning connector are exposed. This battery is *, lasts for about 4 hours and dies after just scrolling facebook and instagram.
