Cateye Strada Cadence gear reviews

I haveused many cateye products icluding lighting systems and cycle computers and found them to consistently do exactly what they claim. Recently I decided to have all my bikes use the same type of computer. I brought three strada cadence units. Within weeks the cadance sensor cable broke on one. Soon after I found a second stopped working because of corrosion of the contacts. The third now stops working because it is loose . I jiggle it and it works again but hard won ks aren't recorded. I can"t believe cateye have released such a rubbish design. I realy can't believe I have three of these pieces of crap.
