I have been using this for the last three months and it is working really well. I had bought 2 cheap ones on ebay and it stopped working in a month. This has worked in my car as well as in laptop and I dont have to worry about adjusting the cable or any of that sort. The cable is quite thick which gives the wear and tear. If someone is looking for a good quality cable at a cheaper price than from Apple store, I would recommend this. 

Question: What is the lenght of this cable?
Answer: If someone is looking for a good quality cable at a cheaper price than from Apple store
