Logitech's Pebble Up travel mouse has a shell you lift into a 35-degree tilt for your wrist

ITHome reported the launch on October 24 with the key spec: a reclining two-form design with a “35° 人体工学倾角,” a 35-degree ergonomic tilt. The mouse measures 105.8 by 59.6 by 30 mm and weighs 79 grams.

ChannelNews describes how it works: “an adjustable upper shell that can be lifted to provide additional hand support during longer working sessions.” Lowered again, “the mouse can be flattened, making it easier to slip into a laptop bag or backpack.”

The bigger internal change is power. The Pebble Up drops the AA cell for “a built-in 290mAh rechargeable lithium-polymer battery, which the company claims can deliver up to 90 days of use on a single charge,” per ChannelNews. It connects over “Bluetooth Low Energy or a Logi Bolt USB receiver” and pairs with “up to three devices.” ITHome lists the sensor at up to 4,000 cpi.

ChannelNews says it’s “only 3g heavier than its predecessor,” the Pebble Mouse 2 M350s, and comes in “Rose Pink, Graphite Gray and Pearl White.” Outside China, “Australian pricing and availability have not yet been announced.”

From Logitech’s pages for the M350s, Lift and its spec sheet, and MX Vertical with its getting-started page.

Logitech’s vertical mice sit at 57 degrees, an angle the Lift page says “places you in what we like to call “natural handshake position”.” The Pebble Up’s 35 degrees is a middle step: more turn than a flat mouse, less than a vertical one, in something that still folds flat.

What Logitech didn’t say. There’s no rating for how many times the shell can be raised and lowered, no US or European price or date, and no word on whether a Bolt receiver comes in the box. The M350s spec sheet says its receiver was “not included.”

What it means for anyone buying gear for people who travel. A mouse that changes shape has a hinge, and a hinge in a laptop bag is the part to watch. For staff who already complain about wrist strain on the road, a 35-degree option in a pocket-size mouse is a cheaper first step than a full vertical mouse that won’t fit the bag.

Why now. Logitech’s ergonomic mice and its travel mice have been separate lines: the Lift and MX Vertical at 57 degrees, the Pebble flat. The Pebble Up is the one in this chart that tries to be both.

The angle is a compromise by design. Whether 35 degrees is enough to matter to a wrist that already hurts is a question for a physical therapist, and Logitech hasn’t published one’s opinion.

ITHome lists it as on sale now in China; everywhere else is still waiting on a date.
