I recently purchased this for my smartphone, and I must say, it has been an excellent investment.The 3-foot length of the cable is just perfect for my needs. It provides enough flexibility without being too long or cumbersome.
I've been looking for a tough wire that could charge my Macbook Pro. Most of them are limited at 40W but I haven't been able to find a tough outer linking one like this for so cheap. It works perfectly.
