These are amazing little adapters! The keychain hook makes them perfect for attaching to your keys, so you always have a charger with you. USB-C is still quite new. So when you visit a friend's house, colleague's office, etc., you can always be sure that you can charge your phone. Almost everyone has microUSB cables lying around for something, and with that little adapter always on your keys, you should be able to use any old microUSB cable to charge your new USB-C phone. Also, they have the right resistance inside, which means your USB-C device should charge safely and without risk of damage. I've been attaching mine to my keys for a few weeks now and it's still working great. The chain is solid and strong, and the plastic adapter doesn't look damaged at all, even when I reach into my key pocket every day. I highly recommend them if you have a USB-C phone, they're great if you need them.
