So far, I'm not getting a good impression of wireless computers. Mine acts just like everyone here was saying. I just went to Radio Shack and got a new battery for the sensor but I havn't tried it out yet. I know it at least sends the signal now as I did spin the wheel. Not sure if it will be giving out crazy readings as before. It worked great for the first few months and then went crazy. Next inline is to reset the entire computer.
