I have used this for almost 4 years now, it's been great to be able to communicate with clients from work without having to drive home or pay parking fees! It has also helped keep my sanity as you can do most of your business in front of your computer instead of being stuck at an office all day. Sometimes there are problems that require me to go into their offices which is annoying but not something i dislike about messenger very much. The only thing I don't like is when there isn't someone available online so you have no choice but to wait around until they answer back. So far it hasn't had any downsides, everything seems fine. If you're looking for a way to stay productive while working remotely then using messenger will help you out immensely. As long as you have good internet connection you should be fine. We use messenger every single day because we both love staying connected even though we live thousands of miles away.
