This cable was purchased for use with my Intus4 model: PTK-640 and it works great with my tablet. I searched for this item after my original cable wore out and caused the tablet to turn on and off intermittently. At work, I use a tablet cable connected to the iMac's USB port. When I use my laptop, I connect it to my MacBook Pro via a USB-C adapter. I haven't had any connection issues and the cable seems pretty solid. I've been using this cable every day since I bought it.
