Have been using private beta for 9 months, and it has simplified my work *so much*! The Magic Calendar straight into the email is also much more respectful of the recipient, truly one-click and transparent. Can't work without it anymore.
I've been using Boomerang for much longer than a year, that's just the longest option this allows me to choose. I use it every day and am still probably underutilizing its capabilities. With it I have been able to be on top of follow ups, handle emails when top of mind but make sure they go out at a more optimal time for response, and with Inbox Pause... Catching up after OOO has been so much easier.
