T1 HE

Keychron's new mouse lets you nudge the trackball to exactly where your thumb lives

Keychron's T1 HE lets you nudge the trackball to exactly where your thumb lives. That's the whole trick, and it's a good one. Most side-ball mice assume your thumb is parked in a standard spot. Keychron instead built a 34mm ball that adjusts positionally, so you're not reaching or stretching. It's a small ergonomic fix that makes a big difference for people whose hands didn't read the spec sheet. The T1 HE looks more like a conventional trackball mouse than Keychron's earlier Nape Pro, which was a slim slab designed to sit flush against a keyboard. This one leans into the familiar Logitech/Kensington shape, but with that one slippery detail nobody else thought to address. Preorders are live now.
