The Backbone One earns a 5 out of 10 on our repairability scale (10 is the easiest to repair):

Using fairly common tools, disassembly is straight-forward with components held in place only with screws.

The Lightning connector can be easily replaced by removing the cover and two screws.

Though no adhesive is used, some screws seem unnecessarily difficult to reach.

Shoulder buttons are soldered onto their respective boards, requiring micro-soldering skills for replacement.

Both joysticks are soldered directly onto the boards, as is the pass-through Lightning port.
