Review on JOYROOM Stylus Pen Replacement Tips Set with Tweezer & Metal Pliers - 6 Disc Nibs for iPhone/iPad/Samsung and All Tablets by Troy Robinson

I bought a joystick grip for Revain and was trying to get replacement tips. I assumed they would fit, considering they showed up when I clicked the link from the stylus, but they didn't. So now I've spent $15 on the wrong attachments and I don't have the correct disc attachments. It would be nice if they could better specify which nibs go with which pens. Or maybe give more than two tips per disc nib pin because they fall out so easily.
