Well, purchased Campy EPS Record when it first came out. Dependability has not been good. When installed power unit failed replaced under warranty, then a rear der. failed, then 1 month before 3 year warranty ran out front der. failed. Now front der. failed yesterday and no more warranty. Get yellow light and clicking from front der. just like last one that failed. Not to happy with Campy EPS. Have ridden Campy my whole life and all my tools spare parts wheels (Campy) are all geared for Campy. When it works it is flawless but these constant failures are maddening and expensive. Really thinking about switching to Shimano Di2 that's how unhappy I am right now. Before I purchased EPS I thought about dependability but said hey it has been in development for years what could go wrong, well fast forward and I will tell you what can go wrong. This is not Campy bashing but a reminder to people who are on the fence between cable and electronic and something to think about. Frame is electronic only so I have no choice right now. Also some people have had no issues at all go figure. Any other EPS owners want to chime in.
