This truly is not intended for the user to replace the roller, but rather, they would like you to pay a lot more to take it in to service! To have a star screw with hole - which is what mine has - not Philips - and under wheels and 10 of them of varying length, and good luck, like Bettie Howard said, getting the driver to fit into the deeper holes! I have no adapter or extension - means you’d have to purchase a special tool. Luckily for me, I didn’t have to replace the roller, but rather sucked a USB cable which quickly wrapped around it. I was trying to salvage it, but after 2.5 screws later, decided it was better to cut the cable!
