Purchased Tally Pro after using the Hario scale for several years for the Brew Assist feature. The scales is well built, easy to use. No longer use the Hario.
If you're like me, and don't want to mux around with math when making that first cup in the morning (or at all), then this scale is fantastic; as it takes all the arithmetic out of assessing your water to coffee ratios. The only disappointment I have is with the timer. It's fine, but I wish it had a countdown feature, that concluded in a subtle beep, for when I swap out the V60 for my full-immersion Clever. It just really annoys me to pull out yet another timer to do this. Otherwise, it's a small criticism for an otherwise fantastic device.
As someone who is new to pour over brewing this precision scale has been so helpful! The automatic timer and weight on the brew assist make this really easy to use.
This is a great scale. The brew assist feature is super helpful and intuitive. I have,however, got stuck a few times as my weights were lost after weighing my beans then placing my brewer on the scale, adding more weight, then pouring my grounds into the brewer before zeroing the scale to account for the brewer’s weight and being lost on my brew ratio. This would otherwise not be an issue but the brew assist feature has made my usual exact measurements entirely haphazard. I’m the problem here…I realize it. I’ll have to rework my work flow.
