As a hesitant buyer, I decided to give this industrial and scientific wiring and connecting product a try .As a result of my tests, I determined that this charging system is impressively efficient for my Samsung Galaxy and MacBook. The charging speed is satisfactory, and the cable is STURDY and well made. However, the price is a bit steep for my liking, but the quality of the product justifies it. Overall, this is a great investment for any tech lover who needs a reliable charging solution..
