The second gen Wireless was better than the first, but that meant that it lasted a year instead of a month. Resetting the communications link between the transmitter and the computer was a regular occurence that we just leasrned to live with. But then after a week of riding in the rain in Brevard the computer never really worked right and finally lost all signs of life even with fresh batteries. At least now the computer works every time we ride and I don't have to hear complaints about the numbers being too small to read.
Team Cross was having similar reset issues. Haven't heard a computer update from Kendy & Wenneth.
