I have used the iPhone 7 Plus Zerolemon Battery Case for over a week now. It is like typical ZeroLemon products. It is very well made. It will give you plenty of extra battery capacity for your iPhone 7 Plus. However you cannot use wired headphones when you are using this case since the case plugs into the Lightning port. It also has a standard micro usb charging port instead of Apple's Lightning Port. One issue I did discover was when I made calls other people had a hard time hearing me when the case was on the phone. It seems like the case protrudes a good distance from the bottom on the phone and my experience was this would make me sound quiet or muffled to those I was trying to talk to.
Overall this is a good product for those that need serious battery life. I was provided this product to test and review for free.
