I got a cupon for a Harbor Freight caliper from a Guns and Ammo magazine. The cupon is for the Pittsgurgh 6" Metric & SAE digital display model. The controls and read out look identical to all the ones sold in the Midway catalog. The cupon price is $9.99 each and a limit of 9. The regular price was $29.99 each, when I got to the store they were on sale for $14.99, and with the cupon they were $9.99 each. I bought 4 of them. One for my self and one each for 3 of my grandsons. I checked one of them out and it gives the same readings as my dial caliper and my micrometer. They also come with two button batteries so there is an extra battery. Only time will tell how they work out. One other good thing is they are made of Stainless Steel.
