What makes OmniPoint switches different?

They are magnetic analog switches whose actuation point you set per key in software, from 0.4 mm to 4 mm. That lets you make movement keys faster and typing keys less sensitive.

No. It connects by a fixed USB cable, about 6.5 ft long, and has no Bluetooth or 2.4 GHz mode.

Does it work without the software?

Yes for basic typing and gaming, but per-key actuation tuning, RGB and the OLED display settings need SteelSeries GG.

Is the wrist rest included?

Yes, a magnetic wrist rest comes in the box along with spare switches.

Full size or tenkeyless?

This is the full-size version with a numpad, media controls and an OLED display. A tenkeyless Apex Pro exists for smaller desks.

How does it compare with the Apex Pro TKL?

Same switches and features in a shorter body without the numpad. The full size suits spreadsheet and data work; the TKL frees desk space for mouse movement.
