Using these to use 1/8" bits in my CNC's router that takes 1/4" bits. They fit perfectly and tighten everything down well with no visible runout. Parts cut on this came out identically to when I used a 1/4" shaft. I don't see it breaking so the only reason I'll need 2 is if I lose 1!

I use it to adapt Dremel tools to my die grinder. Works great so I don't have to buy even more accessories.
