junk dont waste your money

Stay away, The hammer mechanism in these low cost punches does not work often.

It came fast and is exactly what I was looking for

The smaller one is ok - hammers 90% of the time. The bigger one almost never actuates correctly. And I tried to adjust whatever can be adjusted.

Both worked but do not mark metal very well for starting drill bits to keep them from traveling. They would work great for breaking glass in a vehicle if thats what you are looking for. The spring could be stronger.

Great compact solution to marking for drilling or layout plans on multiple surfaces.

Too cheaply built.

Good product and well made.

Larger of the two punches stopped working the day after the return window. Cheap built and not much of a punch even when it works.

There is better out there for sure. Wish I would had spent 5 more dollars.
