Wait, what? It’s split in two?
The Pulsar X2F CrazyLight is a fingertip mouse, and it almost looks like a regular mouse that has been split in two.
The shell is open, and “Engineered for fingertip control” is printed right on the right mouse button.

This is part of Pulsar’s Lab series. A series that, as far as I understand, is about trying out suggestions from their own community.
I dig how the X2F looks. The exposed electronics and skeletal design give it a proper cyberpunk aesthetic. It reminds me of Bungie’s Marathon.
Disclaimer
I tried the mouse at the booth during Moderskeppet, an event by Geeks AB and SweClockers with 1500 geeks on a boat in international waters. Nothing came back with me, so this is a short test at the booth. I only had it in my hand for a short while, but it felt good. It was light and easy to move around, and I found a comfortable grip on it right away. It is also bigger than the Keychron M4 I have tested before.
My mind goes straight to Optimum
But, the X2F immediately reminds me of the iteration project, Zerø mouse, by Ali from Optimum on YouTube. It is the same open, almost skeletal design.
Pulsar claims 29 grams, which is lighter than the Keychron M4 at 35 grams (which I tested last year), and not that far from the Zerø Blade at 22 grams.

Unlike the Zerø mouse, the X2F CrazyLight is available through Scandinavian retailers. No importing, no waiting lists, and local support if something goes wrong. That’s a significant advantage for such an experimental product.

Pulsar LAB in Scandinavia
The CrazyLight is sold under Pulsar LAB, the division for the more experimental products. The regular X2F is 38 grams, and the CrazyLight takes it down to 29 by removing even more of the shell. Pulsar deserves credit for trying such an exciting SKU in the Scandinavian market.

How it holds up over time, and how the open shell behaves against sweaty fingers, is something a full review has to answer. At the time of writing it is on its way into MaxGaming for 2190 NOK, expected in stock October 15.
