Performance Tool W485 Pocket Precision Reference Cards Kit Set, 1 Pack

Sometimes you need to quickly check a conversation and this tool does that task well. I keep the tool in my toolbox top compartment and use the tool regularly when working in the shop.

I keep these with my laptop while working on 3d printing stuff. The measurement conbersions save time and im memorizing them as i go. If you find yourself converting even once a day this is good for you. It instantly converts and you cant help but remember as you use them.

I like the size, but there is way too much useless information on the cards making the needed information very hard to read. Keep a magnifier on hand.

The quality control seems to be lacking. The printing alignment was off on the cards. Fortunately, they are double sided. But overall, this should not have been off as much as they were.

I was a little disappointed with this gets lots of information yes, but the damn writing is so small I had to use a magnifying glass to read it.

Note, these will not fit in your wallet if you were hoping for a reference you could easily carry with you. They're slightly larger than a standard credit card. The card is an otherwise useful reference -- seems like a missed opportunity.

Excellent.
