It works great in a small office or home. I haven't noticed any downsides. However, it can be a bit expensive. We have a small office that is running on a Colo network and it works great. We are able to use all of our devices (phones, computers, printers, etc) on the network easily and securely. We have a lot of sensitive information that needs to be secure and Colo does a great job of that. I would definitely recommend Colo to any small business. We can network all of our computers/phones/printers/etc. using Colo. It is very easy to use and get up and running.
