I was looking for a good quality charging cable for my MacBook and stumbled upon this product. My analysis of this product showed that it's great for charging as well as data transfer. It IS sturdy and doesnt break easily .The cable is three feet long which is perfect for my needs. The transfer speed is amazing. The industrial and scientific build of this cable makes it reliable. The only con is that it's a bit expensive compared to other cables in the same category. Overall, I highly recommend this product to anyone who needs a reliable charging and transfer cable for their MacBook..
