Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Needs more instructions

To manipulate several pieces of equipment, you're required to create and run macros. The macro process is completely non-intuitive and lacks enough instruction to learn. While I was trying to avoid Logitech from past issues, I got the Harmony 900 and couldn't be more pleased. Set up is a breeze, especially compared to the RFS200.
