Good parallels on straight edges

Expensive parallels rarely justify their exorbitant cost. These features are good. They're often not "straight," but you just don't need them! The latch on the case is inconvenient to use. We just leave it closed and unlocked next to the power supply. Get used to it every day. Each parallel has two holes.

Pros
  • Consistent test results
Cons
  • You could have chosen a newer model

Reasonable quality for the price.

I'm just starting out with metalworking and don't need ultra precision equipment. Considering the price I have nothing to complain about. They are well packaged and useful for holding parts at the correct height in a milling machine vise.

Pros
  • Satisfied so far
Cons
  • Write later

Not bad for the money

Just got them recently. After measuring, I found that the parallel surfaces are excellent and within specification. But as another customer pointed out, they are not flat and can be warped to a length of 6 inches with a maximum "bend" of between .050 and .060. In many cases it is less for each piece. I think the Chinese didn't calculate. how to flatten the material and remove the warp. This is the only problem I found with them. Otherwise, I look forward to many years of use and regret not…

Pros
  • Absolutely amazing!
Cons
  • Not bad, but...
