1) I found this software limiting for my purposes - I wanted the software to protect my spreadsheet with macros in, but this is a limitation to the software design. Should work ok if you do not want to use, transfer or build macros however. 2) This company has a no refund policy and limited help function. 3) Whilst the software is advertised on various sites between $25 and $50 I was only able to download it for $100 US.
