KM16 vs. Left-Hand Pad: Is the Cheaper Macropad the Better Buy?
The KM16 Macropad and the Left-Hand Pad are both aimed at giving your off-mouse hand a job, but this isn't a close call: our own product notes say the Left-Hand Pad is our third macropad, and that the KM16 and the EM Mini Pad both cover the same ground better. Buy the KM16 unless you have a specific reason not to.
What each one offers
The Left-Hand Pad is a slim, twelve-key macropad marketed for macOS, aimed at Procreate brush sizes and editing shortcuts like cut and ripple-delete, or, in our context, accept and reject in a diff. It's pitched as the cheapest way to give your off-hand a permanent job: twelve programmable keys and nothing else. The KM16 goes further in every dimension that matters for a hand-shortcut device: sixteen keys in a four-by-four grid, plus three rotary encoders for continuous controls like volume or timeline scrub, remapped entirely in a browser via VIA with layer support, so one held key can swap the whole pad to a second set of assignments.
Why we're not being diplomatic about this
This is one of the few comparisons where the losing side says so itself. There's no equivalent flag on the KM16.
Is there any reason to still want the Left-Hand Pad?
The one thing it has that the KM16 doesn't is a genuinely slim, low-profile shape, and it's aimed specifically at macOS and Procreate users who want a familiar 12-key layout. If your whole workflow is brush-size and layer shortcuts in Procreate and you specifically want that low-profile feel, it's a reasonable niche fit. For agent review, accept, reject, and whatever else you want on hand, the KM16's extra keys and knobs do more without giving up anything the Left-Hand Pad offers besides the slimmer body.
The setup cost you're trading for those extra keys
Buying the KM16 over the Left-Hand Pad isn't free of friction: it arrives with a designer-oriented stock layout, so budget about twenty minutes in VIA before it fits your workflow. The Left-Hand Pad, being simpler, likely needs less configuration out of the box, but less to configure isn't the same as doing more once configured.
Who should skip macropads altogether
If accept and reject are the only two actions you need, both of these are overbuilt. A two-button device or a foot pedal matches the action count without the remapping step, and it costs you nothing to skip macropads entirely until your shortcut list actually grows past what a keyboard already gives you.
