ive some other brand, I hate dusty grip and they last forever, got a belt sander version from home depot years ago
Came bundled on amazon, picked it up after building a DIY version that didn't workout - The bearing tool...used it once or twice, more trouble than it's worth (doesn't work if you use spacers; has helped me once or twice get a bearing out of some hard ass rictas)
Ran out of speed cream and using this right now, works just fine (and was on sale)
Used this forever until the mounting socket popped out/broke, now I keep it around for the re-threader
Best tool, hands down for home/car
Clip this on when I go anywhere
And of course;
Back in the day I'd use wood filler/glue and clamps to fix delams/chips/razor tail, now, meh.
