I have used Cateyes off and on over the years and found them to work pretty well. I have used wireless and wired and prefer wired as I think they are more accurate. I am currently using a Bontrager Trip Three wired as we speak. I purchased it in November 2011 and last week the buttons started to stick. I could not reset the trip reading. Took it back to the LBS and they replaced it for me. We will see how this one works.
