When it works it's fine. Im not sure if I got a bad one before or not but I'm on my second one now. The first week using the first one I had was was great other than the fact Apple makes us jump through these ridiculous hoops to make iPhones compatible to non apple products. However after the first week it was very unreliable in terms of when it would connect to my 5s. In my experience charging cables for iPhone (Apple and off brand) tend to be picky after a few months of use but the second week I had this expensive cable it was almost worthless requiring me to set it up perfectly and very carefully connect and hold for 20 seconds and try not to move it at all as I let it go or it would lose connection and I have to unplug and start over usually taking me an hour or two to get it to work when i did get it to work, which was only 20% off the time.
Pros: It's the only way to mirror your iPhone to your tv without wifi
Cons: It's the only way to mirror your iPhone to your tv without wifi. As with other Apple cables is sensitive & tends to have problems where the cable meets the connection. Expensive. Must be gentle with it. A real pain. Short impractical cable length and design. Drains battery even with charging cable plugged in
