Easy install of Shimano EW-WU111

By: on 7 March 2022
Bought the Bluetooth unit, along with the 150mm wire, the BM-DN100 battery and Plug tool. After reading numerous reviews on Shimano etube application and update of firmware on components, I was prepared for the worst. I was expecting the update to cut out half way, but was pleasantly surprised that the update worked flawlessly. Setup the shifters and linked to the garmin 830 without any issues. Samsung note 10+ was used. Absolutely recommend.
