I liked that we could have our own personal assistant, who was always ready to help me with my messages/emails in real-time! It also helped us stay organized as it allowed you do everything online rather than having files all over your office space or home computer - which is great if anyone needs access remotely (elderly parents). Sometimes when sending an email from work sometimes there would be lags where typing seemed really slow but once sent they were received normally so no problems here!! Nothing at this time of writing other then being able use their service whenever needed without any issues whatso ever. Highly recommended product by far. ! We used them while working together doing business overseas via Skype calls etc., very handy tool especially during times off hours such as weekends & holidays away from family members / loved ones due too distance that communication can't.
