Love the daisy chain capabilities
This is truly a versatile conference system. Each unit is great by itself but when you need to cover a larger space you can more units to the conversation. That is a great feature to have. Also, you can use 1 power source now instead of having to power each conference unit. Thanks to Gerald (I think that was his name) at The Telecom Spot for explaining how it all works.

daisy chaining capabilities
easy to setup

none that I can think of right now
