Good production especially for a first time video.
1. There wasn’t an actual functional review of the product, would be nice even if you simply compared perceived vibration by tapping the top shelf with and without the platform.
2. You repeated yourself a couple times, in a short video it becomes obvious that it’s not as polished. “... in the game for many years” or something of the sort.
3. In the end, in the game of audio outside of work, my passion is audio and music. Minor slips. But I think in time you have some good content.
keep at it!
