5/5 Even if it didn't have bluetooth

I'm going to be 100% honest, I bought this scale because it looks badass. It's super sleek, and very minimalist looking. It is, of course, also a great scale. It's very accurate and very responsive. I've had it for a year and used it every day. What I haven't used everyday is the bluetooth functionality. I used that for the first week of ownership and then never really bothered again. It's fun, but I can't be bothered to turn the app on everytime I want to make a coffee. I love that I can view flowrate while brewing to try and keep my pour consistent. After trying another scale for espresso, I've decided that I'm going to replace the lesser scale with a Lunar since I've been so blown away by my Pearl. If I could buy a cheaper one without bluetooth, I would in a heart beat.

So far so good!

Used it for about a month now and it hits the spot. The ability to update the software through the mobile app is pretty sweet - hopefully that means I won't need to upgrade/switch this scale out for a long time.

The best coffee scale out there!

Let's admit it: this scale is not cheap. But you get what you pay for!
It's well built, precise and fast. The dot-matrix display is an improvement from the Pearl's display.
The phone apps would need some love... they're not updated often, but I don't really use the apps anyway. I use the app once in a while to update the firmware or upload a new brewguide to the scale.
It's a bit large (about the same as the Fellow Stagg EKG heating pad, for reference), but that's a nice size for pourovers with decanters or a Chemex.
