The HTC Vive Repairability Score: 8 out of 10 (10 is best):

Although it's a complicated bit of kit, the headset breaks down readily and without damage.

The head strap and face pads are removable and don't incorporate any sensors or electronics that might be prone to failure.

Standard Phillips and Torx screws are used throughout the headset, controllers, and base stations.

Reuse of the touchpad hardware from the Steam Controller means some replacement components are likely already available.

The large number of components, many of them quite delicate, means you'll want a service manual before attempting repairs.

Adhesive is used sparingly, but secures the lenses, Lighthouse base station covers, and sensor arrays.
