I loved how this product was easy to set up and use. There were some downsides - sometimes it could take several minutes before you see an update after making edits or changes in your spreadsheet. If someone else makes updates to this file without sending notifications through email that may not show until hours later! Also, we can't share documents with other users unless they are logged into Sharepoint as well. With these two issues addressed (sharing and notification), it has increased my efficiency by a large margin. We had previously used Microsoft Excel for all of our spreadsheets but realized there must be a better way!
