    1,500 hour blade life? That’s crazy good compared to what we’re using now 🤯

    Haha they clearly never tried shredding our tough industrial scrap. Wonder how it handles real-world abuse.

    The AI optimization module seems overpriced. Basic maintenance scheduling should be included standard.
