### ⭐⭐⭐⭐⭐ does what it is supposed to do

### ⭐⭐⭐ Yes and No
*by E***. on August 4, 2024*

This is used to connect and disconnect wires for a Di2 12 speed. The wireless shifter generation. Do you need it? Maybe. I got it to update my shifters. The wires can be pulled out by hand, without the tool. Should you use it, probably. For me it was easier not to. I just used a long wire and connected it from the battery to the controls to do my update. I never used the tool.
