Original review updated by user May 11, 2021 I've been using the mobile scan and recently, EVERY TIME I get the audit alert. Now, I have to go find one of those scanners and MAYBE it'll go through. The last time, I just went directly to the scanner and STILL had to be audited for SIX items! And Marty is ALWAYS in the way causing jams - get RID of it. Slips on a wet floor are far more dangerous than a stupid piece of paper. For the money you paid for it, Marty should detect spills User's recommendation: F.
