Checkpoint has been in business since 1995 and purchased in 2003 by Precision Designed Products, a company with much greater manufacturing and distributing capabilities. As a result, we are now able to produce the Checkpoint products at a much better price and are able to pass those saving onto you. As with all Checkpoint products, they are CNC-machined. Anodized T-6061 aluminum and has a lifetime warranty on the body. We extend a year warranty to cover the vials (after which time, we have a $4 per vial fee to replace and recalibrate). All Checkpoint packaging has been redesigned for "peg friendliness" and ease in merchandising.
