good for money

I bought these for a project and they work great. They're not very well finished, but they were parallel. Not too bad for the money. I won't be too disappointed if someone gets hurt.

Pros
  • Housed in a plastic case labeled size range
Cons
  • disappearing

Disgusting for a new item

I won't be returning the parallels as I already use one of these but I think the seller should know it's a 2 inch cut or -Tear gives back part of a vinyl storage box - disgusting for a brand new item.

Pros
  • Made from precision ground tool steel.; Expands easily to hole size for quick reference measurements
Cons
  • Not bad but...

Bad steel, no tools.

Am I wrong in assuming that China has the same standards for tool steel as the US? In any case, I work with hard materials in my workshop (4140, P20, Maxel, etc.), these parallels are only suitable for aluminum. I pulled out my file and slightly removed the corner. If you even get mild steel shavings under one of these, you'll be out of the parallel set before you know it. I will come back as soon as I get the opportunity. A finely sanded surface looks and feels terrible. Maybe they don't…

Pros
  • Expands slightly in holes for quick reference measurements
Cons
  • Slightly crumpled
