I've had one for about 4 years and Chrono'd dozens of guns with it - and never shot it! Amazing what a bit of care can do!

I've been looking at several Chronos lately just as a bit of an interest and for £50 it's hard to beat these, and the customer service is excellent.

I lso bought the cable and software to put on an android phone, so I can get full print outs, graphs and chrono strings.
