Very Quick, saves me a lot of time. I regularly get pdf's that need to be completed and sent back. Now I can upload, fill out and return in a fraction of the time. Since the data is typed, I never get a question about what I wrote.

Some frustration with the search option. I was searching for W-2 for 2020. Could not find, so chatted. I'd solved my problem by the time the chat person responded. Today I was looking for a fillable PPP Loan Forgiveness form. It may be there, but the search said no results.
