One-line verdict

For everyday pour-over and drip users who want a straightforward, accurate scale with timer at a solid mid-budget price, it delivers reliable performance the Greater Goods beats on price but lacks the slim espresso fit and advanced modes of the Hario Polaris.

How it compares

vs Greater Goods Precision ($35): Bonavita wins on faster response and timer quality, Greater Goods wins on price and larger platform
vs Hario Polaris ($89): Bonavita wins on value and battery life, Hario wins on ultra-slim portafilter compatibility
