Ive had the lighting cable and the power core for about 1-2 years now and it's been amazing. I love there these two thing have flown around the world with me and they have been my go to things when I need to charge up my phone. The screen protectors I got recently and I love then. Two came in the package and I've justs used 1. The instructions were very simple and easy to do that my 5 year old can do it on her own. I'm just very satisfied with your products and keep on doing an amazing job.
