gift for my dad

This iPhone 6 & 6s Battery Case from SinoPro is Fantastic!

The case looks great! It's very slim & lightweight so it doesn't add much bulk or weight to you phone which I really like!
There is also no installation of any kind required, just plug & play!

The phone feels very secure & protected in the case & it works great!
It has easily doubled the amount of talk time & web surfing I get!
I really like the fact that there is no need to remove the case to sync or charge the phone as well as the case!
It has a lightning port on the bottom & a USB port on the side so you can both, charge & sync your phone as well as charge the case at the same time!

Another simple but great feature is the LED power bar on the case. It shows you have much power is left in the case so you dead get stuck with a drained battery or case!
This case even has a small kick stand which has come in handy when I wanted to set the phone down while watching a video. No more looking for something to lean my phone against & hoping it won't fall!
