I echo what most of the reviewers have said about this application with a few caveats. I have had passed issues with locations or containers losing their items. To me this is a serious issue and requires me to go back and make a redo on everything. Doing this on a regular basis is ridiculous and if this is indeed a problem with the app and it should be pulled from the shelf. If it is an operator issue then the operator should be educated or shown properly or directed to where there is resolution. Initially the developer was extremely diligent and working with me on this but now its as if he fell off the side of the earth, No responses no anything from him, too bad.
