I currently have an MX500. The remote is about 3 years old and occasionally loses its mind. Certain function work sometimes, other times they don't. I love this remote. The look, the feel, does about everything I want it to do. I contacted Universal Remote about 6 months ago when it started losing capacity to do certain funtions. They suggested I send it in for service or replace it. I'm looking at a couple of options. The MX 6oo, which I understand is basically the same remote as the 500 or upgrading to the MX700. Is anyone out there using the MX700? I really don't need extra macros as I'm not using all available on the 500. I just hate to replace the 500 with the same thing.... you know... big, better??? ANY OPINIONS ON THIS?
