Shimano DI2 D-Fly ANT+ and Bluetooth wireless connection box IEWWU111

Very good (Translated review)

Fits perfectly to a Di2 Dura Ace R9150 group. Received very quickly! Perfect (Translated review)

Mounted with Ace 9150 2x11v Di2 Group. Bought to replace the failure of the buttons on my Wahoo Bolt v2 counter. The buttons on the G/D hoods replace the G/D buttons of the counter. It saved me from changing the counter. Safer because you keep your hands on the handlebars and can monitor the battery level and chain alignment on the counter. A bit expensive for such a small electronic component. (Translated review)

Maybe a gadget for the amateur that I am, but it allows me to keep my Di2 up to date (which deserved it). Easy to install, but don't forget to order the SD50 cable. Moreover, the price is very interesting on MV. (Translated review)

Very practical for navigating within a counter. See the positions of the engaged gears. (Translated review)

Very practical because I no longer need to let go of the handlebars to change the screens of my GPS. You have to press the buttons on the hoods well, which was my case with my BMC bike. (Translated review)

Perfect for checking the battery status. (Translated review)

Small, so easy to slip into the tube with the battery and easy to connect (Translated review)

Ideal for obtaining various information from the Di2 group on your counter: battery status, gears, etc... (Translated review)

Function very well (Translated review)
