Just another two cents into the Acaia recommendations. I've had a pearl for 6ish years, and I really like it (Full disclosure, I didn't pay for it but was given it at an event I worked, I would defo buy a replacement if it died though!) I use it pretty much every day for brewing filter, baking and general kitchen use. I'm clumsy as hell, so I think it's done a killer job surviving this long! I don't use any of the app connectivity, so probably wasted on me. Do enjoy the timer though, it's much easier than digging my phone out and keeping the screen alive to show the timer. I have used it for weighing portafilters, and it's totally fine for that, I just find it's a bit slow to tare for my liking. But that's also usually making espresso at events or in a commercial situation, so not really home use! I'm used to ohaus scientific scales with the "no touchy" tare at work as well, so I'm defo ruined for all other scales!
