I have done a few.It all depends on the stores and the number of items. I've done a few that were grocery stores with only about 50 items in one department, They were a snap. Then I've done one in a large outdoor store and it was murder, items in about 50 departments in all different areas of a really large store. That one took me forever. The app is very easy to use. Once you have finished the items, you are done. I've used the app for audits for two different MSC's.
