Seriously? I have been using mx 800s and 850s for years and when the 950 came out I got 5 of them to sell. Well I still have 4 over a year later because I can not get them to work reliably with RF. I have tried on a number of occasions and the results have been spotty at best. Ive sold over 200 URC devices between th3 mx600-650-350-800-850-900 and for the most part until the recall of the mrf250 last year had little problems. Now it seems the only thing that works is RTI.......... I really like the URC stuff and the price point is much different then the RTI stuff. Anyone...?..?....?
