What I received was NOT what is pictured, not even close. The product picture clearly shows a thumb wheel adjuster. There's no thumb wheel on what I got. As if that wasn't bad enough I cannot believe what I received is a Brown&Sharpe. Talk about being cheaply made. I have an older Brown and Sharpe and I bought this because sometimes I need to have two calipers on hand and wanted a quality instrument. well I guess I'll have to look elsewhere. I am sending this POS back! For those out there who are content with second/third rate calipers and enjoy name calling GOOD for you I am glad you are happy with an inferior product and receiving something you didn't order. I saw a thumb wheel in the pictured product description so I want what is shown not a cheaper substitute the seller decides to send instead. I also own an older pair of B&S calipers that are first rate. These newer ones are a mere shadow when compared  with the older ones. In fact a pair of RCBS China made that I also own is a cut above.  So go ahead and be a cheerleader for junk. Buy a hundred pairs of these new B&S. You will need them. What I said is 100% true, ignore my advice at your own risk!
