speaking of my experience, been using 3 screen protectors for the past 4 months, starting with nilkin tempered glass, it was good, but when my rhinoshield appear, upon lift, cracked everywhere, and rhinoshield is seriously overpriced, got scratched, not even like a month or so, and requires great application skills, so mine was screwed up, so i toss it away, living it with naked, and realized the screen caught some minor hairline scratch, no choice, so i went for x-one, so far so good, hopefully its last.

Plastic screen protectors are always prone to scratches regardless of brand

Spigen Glazz bro. RM103 - 2 pieces in box. I'm using this one. Spigen is SGP.

Benks none 3D not full screen one is not bad. Remember Er it's not the fulls screen type, it's the type that only covers the screen, not edge to edge.

Its usually less than 2 hours, and its definitely faster than using the 5W apple charger and cable.

You also need to understand that 0% - 80% capacity, the device will be charging at full speed. When the capacity reaches 80% the charge rate will be trottled down and finally at 95% it will go down further to trickle charging. This is done to safeguard the battery in the long run.

Anyway, I have been using an ipad charger to charge my ip4, 5s, 6, 6+ and 7 with no ill effects . and apart from the ip7, the rest are all >more than 2 years old. So long as the power feed is stable and clean, it should be good for the device. I also have one of those Pineng 11200mah power banks. But when ever I use the ipad charger to charge it, it still needs a solid 10-11hours for full charge. This means that the device circuitry can only receive max 1amp max current. Power bank nowadays expecially those with Qualcomm 3.0 can take much higher charge rates thus minimising charging time tremendously.

I think it's called the Benks KR+, I'm using it now. The front sensor and camera cutout is perfect. I have one extra piece, let me know if you're interested
