I really like the concept of this pizza oven. I think it has great potential. My comments are about the videos - not the pizza cooker. And my comments apply to many videos beyond these.
Folks who make video need to understand that the audio is even more important than the video. People will watch "bad" video much more than video with bad audio. Wind noise, other noise, varying levels, and poor commentary will send viewers away much faster than dark video, bad colors, etc. In this case the wind noise at the beginning makes it painful to watch.
I always advocate listening to the audio when you take your project in for production. If it is not perfect, consider cutting the audio track and doing a voice over. This lets you say what you wanted to say, get rid of "umms & ahhhs" and cut out bad background or wind noises. It also lets you edit the video to the key scenes and then match your voice over to the action. This is much easier than trying to edit the video, but keep the audio in synch. You can add a music track if you wish (be careful of copyright laws) and it will be much more impactful for the viewer.
Thanks for posting, pz - I am really getting to like this cooker!
