What are the major differences that make the retail price of the MX-800 more than the MX-700 Solo?
The MX-800 can transmit commands via RF to the MRF-200, which then sends out IR commands to the devices. You can use the remote anywhere within range (including through walls, from different floors, and from outside), but only with IR devices. The MX-800 and MX-700 can both control up to 20 devices. Each device can have up to 4 LCD pages of custom buttons plus all of the hard buttons programmed.
