I was about to place a digi-key order a couple of weeks ago in order to buy the molex crimper for the vertical power molex connectors when I came across a document on the vertical power website that stated Vertical Power has molex (professional series) crimpers available for free rental. I figured it was one of those marketing lines that when you try to actually contact them they either ignore you or tell you that they don't have anything available.
To my surprise I was completely wrong. They shipped the crimper out the day after I contacted them, and here I am 1 week later with all of my connectors done!
