They're up and running since share holders meeting. Don't know how long instalation takes. Takes about 45 minutes to do our survey on a grocery store, than they crunch the numbers do paperwork and submit. Not sure how hotel works, but would assume do one room and multiply by how ever many rooms, than office ,lobby etc etc etc etc. Than crunch numbers etc etc etc So really instalation is the mayor time consuming factor. Alex, Byron, and Others will be at that convention. Hope we get the entire group.
