I would wonder, the requests in past - how much you had recurring clients vs new ones?
Could it be seasonal - less diy activities in winter (don’t know why though :D).
For myself - I order one from your previous “left overs” - was quite pricey,have to admit. But I spent a week of very intensive research of local capabilities in Latvia and the best what I could found was - applying film on regular glass.
Once received, the quality of mirror was outstanding. My first experience with them, but is such a wow feeling. (plus shipping packaging was perfect either - can understand it costs what it costs, but then it gets safely delivered).
Don’t know if/when I would be coming back ordering another one. I have a feeling I may eventually, but don’t know when. Long answer short - maybe need to be looking on smart home enthusiasts who has diy installations (like openhab and has), raspberries hanging around and have not thought of MM idea? Maybe having MMM binding in openhab/has libraries would provoke them to coming in magicmirror.builders community and users of your outstanding glass-mirrors? just 2c for brainstorm.
Thank you for your words
