    No issues… arrived as advertised…came in molded case with foam inserts…. overall quality seems good ….if I had to be picky, the only issue i think is I think the adjusting wheel could have a little less play in it…..seems to be accurate

    I have been a Machinist for 39 years there was key word WAS a day when Starret tools were the top quality measuring products in the industry. That day has passed. For 150 dollars these thins are Hobby grade at best. I could have saved 130 bucks and bought a set like this at Harbor Frieght for 20 bucks. Mititoyo for me all the way fom here on out Amazon was out of stock never again will I buy Starrett anything again
