David, I have been very happy with mine.
I originally bought mine to use with my tiny Leitz Minolta CL system but found it so small, accurate and convenient that I carry it constantly and use it with all of my cameras. Like you, I wear it pocketwatch style, with it's cord hooked on a belt loop and the meter in my hip pocket when not in use. I always forget to turn off the alarm so every day at noon I find myself asking "What the h*ll is that d*mned beeping noise?"
Recently, the top button started getting a little unreliable, (I think this was due to condensation from bringing inside after using it to check the minimum temperature one sub-zero Winter night). I dropped it off at Bogen with only my name and telephone number jotted on a piece of paper and they called me the following morning that it was ready. I wish that all photo repairs could be done so casually, quickly and cheaply. I've had similar excellent service from them over the years with a couple of tripod repairs.
Good luck with it.
