Anyone use the RCBS® AmmoMaster Chronograph?

I was originally put off by the plastic parts, but if it works who cares. What I was attracted to was the detachable keypad display. Where I shoot it is a public shooting range, only see one person with a chrono in over 3 years shooting there.

I can have the display at the shooting bench and write down the numbers, and have a camera tripod to mount it.
