Extruder Filament Sensor Hall Switch Board with Flexible Cable

As a software guy, I'm quite particular about my gear, and this sensor has honestly saved me from a few disasters already. The real-time monitoring works great, pausing the printer smartly when something's off. Installation was a breeze; the cable is flexible enough to route easily in tight spaces. It's made my printing setup way more reliable, and I don't have to babysit it anymore. For the price, it's a solid add-on that delivers on its promises, and I'd recommend it to anyone looking to avoid wasted time and filament.
- Pros: Honestly, this thing is a lifesaver for my printer. It catches issues before they wreck a print, and the setup was super easy with the flexible cable that fits right in. I can finally start a long job and walk away without worrying, which is a huge relief.
