I am new here, but I wanted everyone to know that LEVELCHROME has great customer service. I know this should go in another place, but more people read this one. I work on wide format engineering copiers that se JIS screws. I ordered 5 different Vessel ph2 drivers to compare. LEVELCHROME sent me an email that I must be comparing them and are sending me some sunflag and anex free to try too. I was buying Wiha, but the customer service from levelchrom is great.
