I guess all that can be said about anything, no matter what it is, is it's not perfect. from my personnel observation and experience I have not had a single glitch in over 2 years. Nor have I heard of anyone in my club having any. Having read these forums for some time I have heard of many incidents regarding 72 and experienced a few over the years. My conclusions therefore are definitly in favor of Spectrum. they have many things in their favor over 72. Model match for one. Strangely unfortunetly every so often something goes wrong with every car I've ever owned, as well as various things in my home. Just don't know why nothing is perfect??? Can't speak for other 2.4 systems since never used them.
