can be a little tricky to set up at first but I do love the ease of having a form filled out and emailed rather than printing, hand writing and then scanning to save to the cloud!

Great way to electronically complete forms!
I hate printing and re-uploading forms. This is a great way to eliminate that. Also good for converting static files to dynamic documents!
It can be finicky and annoying to use if the computer doesn't have the right software.
