Contact us

Send us a video. A surgeon sends back feedback.

It’s the best thing we offer: record yourself practicing on your GSB, attach it below, and a verified surgical faculty member will review your technique.

Record

Film a rep on your box — phone camera is fine.

Attach & send

Add the video to this form with a note on what you want checked.

Get feedback

A surgeon reviews it and replies with specific corrections.

Not sending a video? Use the same form for guidance on building a box, bringing the GSB to your program, or setting up your app account. We read everything.

Get in touch

We reply within a few days — faster if there’s a knot involved.
