I like how good they worked

The tool is inconsistent. I rarely works as intended.

It malfunctioned on 3rd use, not sure how long it will last.

After 1-2 week of use.

Given the cost I didnt expect a high caliber tool, but I figured since there would be *two* of them I would at least wind up with 1 usable tool. I was wrong. The first punch never fires and is functionally just an awl. The second punch fired *1* time and immediately became stuck so now its functionally a paper weight. I could likely find a way to fix it but Id rather not spend time fixing a tool before its first real use. Will return and purchase something else.

These seem well-built and sturdy, although the mechanism is a little stiff (maybe after I use it for a while, it will become smoother). I used it to make a few drill guides in a wood beam, and it worked just fine. One small negative is that if you dont know how to adjust the tension, these came with no instructions whatsoever. Fortunately its not hard to find this info online (or figure it out): the farther you unscrew the base (the end farthest away from the point) the less tension there is on the mechanism and the less force needed.

cheap, but junk. ordered first pair, one worked. ordered replacement pair on amazon, neither worked.

If you have to drill holes in ...... you can simply start drilling and hope the drill bit actually goes in straight. On metal or on rounded surface you know the drill bit will dance around before catching and scraping up the surface as it goes. These center punches are spring loaded so you simply place it where you want to drill press and it leaves an indent keeping your drill bit centered and straight. A must have for anyone working on metal or plastics. Good quality tool which when you learn how to use you wont ever not want to be without.

Its easy to use for pushing down but if you have a project which requires a push upwards or sideways, this tool isnt strong enough.
