プレシジョンミラー

I set this up under my portafilter and it’s amazing being able to watch the bottom of the basket and see exactly when the flow starts to channel. The reflective surface is clear and doesn’t distort the image at all.

I was skeptical about needing a mirror for espresso, but the angle of this one lets me actually see the extraction stream without craning my neck. The reflective surface is clear and doesn't distort the view of the flow. It's made dialing in my shots noticeably easier.

Tilted this under my machine and finally saw exactly when the espresso stream starts to blond. The curve of the mirror makes it easy to spot channeling without craning my neck. It's a small upgrade that's already improved my pulls.
