I just purchased your tolerance calculator. I am in the U.S. and we use imperial units and your software only accepts metric. Since your product only works with metric units, I want a refund. Below is my receipt.

I’m afraid we are not permitted (by our contributors) to give refunds unless it can be shown that we have misled a customer, and on the calculator page (http://calqlata.com/proddetail.asp?prod=00022), we clearly state “The diameters accommodated in the machining tolerances calculator are 0 to 500mm and the dimensions are provided in millimetres and inches.”

Now that you have the working software you could continue to use it simply by making your conversion (multiply your diameter by 25.4) and the results are printed in inches. If we refund your purchase price, you will have been supplied with a working copy of our calculator free of charge.

Moreover, if after having purchased the calculator you felt that Imperial input values would be a useful modification, you could have issued a request for such an update, and if we had taken you up on such a request, we would have provided you with a free copy of the upgraded calculator.
