I've used an SK168-ll from MIS for the past couple of years.  The last time
I used it the light was a bit sluggish but it worked.  Today I can't get the
light, red or green, to come on.  Do these things eventually just stop
working?  If that's the case I'll re-order from MIS. It's too late for their
tech support now and I'm an impatient sort when it comes to questions.
Thanks.
