Precision End Cap Set

Good looking product, have not used them so far

fun to spin. not so fun to switch out.

Got this for my husband for Christmas. He likes spinny go weeeee. But they're hard to take off without scratching the material.

Too risky

Don't buy if you don't want to scratch your screwdriver. It's very hard to unscrew the one it sold with. I recommend using wrench, cloth and rubber gloves, don't even try without them. Ensure to fit it tight, otherwise it won't spin as good as out of the box.
