Review on Sealed Power SPY1 Plastigage by Vashod Reed

I am an engine/machine repairer and have ordered several boxes of this product from many other Amazon sellers and the picture showed a few stitches. For the price you pay from this retailer, you can buy a whole box of 12 from others here on Amazon. I was unhappy that I only found 1 piece. If it was for 1 piece it should have said it in the comments section and also shouldn't have shown the full box in the picture. I would not recommend this seller!
