Bests & Worsts Reviews from Amazon

I'm a long-time cycle computer user. I recently bought this Cateye model to use on a new bicycle. My previous computer a Cateye Astrale with cadence that worked well for several years. My disappointment with this computer began on my first ride: I noticed that the refresh rate is quite slow, especially with the cadence function. Since my previous computer was very fast (though also inexpensive), this was a big disappointment. Secondly, while there is a dual-display on this model (speed display large, other functions small), not being able to toggle between speed and cadence as the main display has been a let-down, since I typically am more concerned with cadence than speed at any given time. They can, however, be displayed simultaneously, which is the mode I typically use with this computer. Lastly, and most importantly, the contacts between the computer head and the mounting bracket are not reliable. Several times per ride I notice that either my speed or cadence, or both are reading zero, and I have to wiggle the computer in the bracket to get the reading to come back. This is not only inconvenient and creates inaccurate records of time and average speed for my rides, but is dangerous as well, since I'm taking my eyes off the road as I fiddle with the computer. With other units, this poor contact is typical in wet weather, or when computers get aged (the contacts wearing from vibration), but on a month-old unit, I find it unacceptable. I'll be ridding my bike of this computer ASAP.
