Di2 Wireless Unit feedback
Considering getting the Shimano Di2 Wireless Unit for my new bike. However, one of the guys at my LBS said he wouldn't recommend it due to its bugs and inconsistent performance. He also said that it had the tenancy to malfunction and shut down the entire Di2 system (shifting and all). I'd like to have the ability to control my head unit with the shifter buttons and perform updates with my phone, but not at the expense of total system failure.
Does anyone have recent experience with the product? Wondering if some of these issues were more prevalent in early versions, and if they have since worked out some of the kinks.
Thanks!
