Probably the easiest way to get a signature.
Scan, upload, define signature space, sign, define signature space for second party, send email, wait, get the document back with both signatures.
Generally, it is quite good value for the money (i am on their single user plan), they definitely need to provide tips or tour, at least for their windows app because it is hard to start using the product. I need only a simple signature from my clients, so I haven’t gone deeper in their features.
