This cordless Dremel clone is so cheap you can buy an extra and use it as a milk frother

They are garbage. The ‘ball end’ isn’t anything near that. There’s burrs all over the place. The coating is uneven and flawed. It’s going to take a half hour of cleanup with some sandpaper and a deburring tool before the two sets will be useable. I’m not sure the ball end ever will be on some of the smaller ones as they were never formed properly–they’re too long to act like a ball. Well, maybe a football…

Huh. Mine aren’t like that at all.

I’ve owned a bunch of calipers over the years. Some good and some crap. I’ve finally settled on having two kinds of calipers kicking around: >$100 units (mitutoyo/starrett - carefully put away in their case) and plastic $1 vernier calipers, now somehow at the bottomed of every drawer.

All cheap digital calipers I’ve owned ate their batteries in just a few months. It seems like they’re always dead. AVE covered this problem in a youtube video a while back. If the tacklife digital calipers are different in this regard, then I’m interested to know about it.
