Apparently I'm very hard on my charging cords without even realizing it. Luckily, I found this one that seems much more durable than the typical ones I get locally. The tangle free feature makes it so the wires inside are protected much better. This means it is harder for me to break a wire by shoving the cord into my purse or bag, which is usually what happens. I also noticed that there is more protection at the ends where the cord connects to the connector for either the USB or the lightening slot. This is a huge plus too because this is where most cords and wires are move vulnerable and where the bulk of mine have broken. Great overall product and I'm sure I'll be replacing all my other cords with this type of cord.
