Needed a replacement cable for my Intuos Pro M (PTH651) after the USB A side somehow got damaged between my school trips. I ordered this cable and fortunately first class delivery was offered. My biggest concern was whether it would fit in the tablet's narrow USB port and I can say it's not a problem. The cable is good and tight! Even better than the regular rectangular cable! Having fixed my first problem, I now hope this product's wiring will stand the test of time.
