Nothing wrong with this product. Works perfectly... I bought this item to replace an old Shimano electronic shifter that failed after about 15 years. They don't make it anymore so this was my best option for replacement. My only gripe is that it's noisy. The original Shimano was silent, and this one sounds like a fishing reel. Not surprising Shimano probably makes alone more money from their fishing reels than they do these things.

Shimanu is a great maker of bicycle parts. This is no exception.
