Developed at the "Ergo Lab" at Logitech's headquarters in Switzerland, you can type in a natural and relaxed posture while relieving unreasonable twists and bends in your wrists and tension.

The unit Adopts a key layout in which the left and right keys are divided at an angle of 25 ° so that a triangle can be created with the left and right hands without twisting the wrist. The body has a streamlined design that is raised in a chevron shape at an angle of 12 °, and a similarly curved palm rest is integrated. Logitech offers 54% higher wrist support while reducing wrist bending by 25% compared to previous models.

The layout is a 115-key layout, and the switch uses a pantograph mechanism. Key pitch 18 mm, key stroke 1.8 mm. The palm rest has a three-layer structure in which a high-resilience material is layered on a shape memory material and coated with a highly durable fabric. It is possible to support the wrist while distributing body pressure, and there is also a tilt leg that lifts the wrist at the bottom of the palm rest. The connection interface supports 2.4GHz Logitech Unifying and Bluetooth 5.0 LE, and the maximum communication distance is 10m. The power supply uses 2 AAA batteries, and the battery life is up to 2 years.
