better with my fingers!

Ground surfaces had wavy grinding marks, Cla 35 definitely did not match any of the gauges, and the advertised size tolerance of .0002 was exceeded by .00008 inches by almost .0001 or 25%. In addition, the clearance had chamfers that protruded above the ground. You couldn't have two sensors ringing together, gross. I could do better with my fingers!

Pros
  • New
Cons
  • Slightly torn

Great for our purposes.

Great value for money. We need them to calibrate the paper cutter - our tolerance is in the range of 0.1-0.5mm. For our purposes, this set works absolutely perfectly. There's no noticeable difference between them, but we haven't measured them. They came in an odd spaceline which we ridiculously took off so they were clean and ready to use within minutes of delivery and were well protected during the shipping process. Would buy again.

Pros
  • Great for a small home
Cons
  • Questionable purchase for the elderly

Good for my woodworking

I use them all the time in my woodworking hobby. From holding items while gluing to working as heavy sanding blocks and holding items under a small power drill. They come in pairs, and to my inexperienced eye the pairs appear identical. I haven't measured them with calipers or anything as I don't use them for precision purposes, but it's nice to have blocks that I know are square or close enough. If you do serious editing work. It can be worth investing in higher quality blocks, but they're…

Pros
  • Easy installation
Cons
  • There are other interesting options.
