Headphone plug broke off in headphone jack of Chromebook. Fixed it because no sound would play through Chromebook speakers. Chromebook without sound is pretty much unusable in a 1:1 school.
It worked as described.
Be sure to watch the Instructions video on the website where you order the Gripstick. You really do need to tap the Gripstick into the port. I used the end of a screwdriver, not a hammer. It took a couple of tries. I noticed the broken piece getting closer to the opening each try. I did us a needle nose pliers to squeeze just a little tighter, but no so tight as to bend or crimp the Gripstick.
