Dan,
Our experience at Montclair State is the same as John's. The people at Vernier
are great to work with, from the owners on down. Our ULI's are between 10 and 1
year old. Had we not had success with the equipment we would have switched.
Recently we decided to switch platforms from Mac to PC. We had some software ,
newer versions of programs, which were for the Mac. It was still in the box. I
called and without hesitation, they agreed to switch copies with us. The PC and
Mac versions cost the same. We have e-mailed Dave Vernier with questions from
time to time. Always pleased with he response.
