What is wrong with their video hosting provider? It is randomly buffering every few seconds for like 5 seconds or more. If they don't want to use YouTube, at least make sure your provider doesn't provide a significantly degraded experience.
Drive is probably a better term than disk for storage.
Quick thoughts:
1. It's 2021. Why use foam for packing?
2. The video is slow to load and buffers much. Why not just host it on Vimeo and let them handle the surge?
3. David Hammer's favicon is blank.
4. You should offer (for a $Reasonable value) for the privacy screen to come preinstalled.
