Our take 43g, high hump, narrow waist — a claw platform, sold as one
Pulsar's X2N CrazyLight doesn't pretend to be everything. The official copy is a sizing chart with an opinion: 43 grams with the included dot skates, 45 with regular feet, a high hump and cinched waist 'perfectly optimized for claw and relaxed claw' — the lightest entry in the X2 family and the most specific shape in this whole batch. Ten pros agreed enough to main it.
The weight story is a hardware story. Forty-three grams in a solid (non-perforated) shell comes from a 0.7mm-class thin-wall chassis and an obsessive parts list — dot skates (sixteen UHMW-PE pucks ship in the box) shave the two grams a full-size skate set costs, which is why Pulsar prints 43/45 rather than picking one. The platform is current-gen regardless of the featherweight: XS-1 flagship sensor at 32,000 DPI / 750 IPS / 50G with Motion Sync and a 20K FPS Turbo Mode, 100-million-click Pulsar optical switches, TTC Gold dust-proof encoder, LOD at 0.7/1/2mm, and DPI fine-tuning in ten-unit steps. The 8K dongle is included, not an accessory; wireless runs to 8000Hz, and config works through Pulsar Fusion2/web driver or mouse-bottom buttons. At 124 x 65.5 x 40mm the Medium is mid-size with a rear that rewards claw locking — and the official FAQ's 'Is it good for claw grip?' answers itself.
The short version: the sanest ultralight in this batch — 43–45g solid shell, flagship sensor, 8K receiver included, and a shape Pulsar doesn't oversell: buy this for claw, don't buy it for palm, and swap skates before you swap mice.
The dot-skate configuration glides differently than full-size feet (more scratch-in, less mass) — the 43g number is only as real as the skate choice you make.
Palm-dominant grips get no side shelf here; the narrow waist is a claw feature that reads as absence of support to anything planted.
Who it's for
- Aggressive claw and fingertip players — the hump-and-waist geometry is the reason it exists.
- Sub-45g solid-shell seekers who won't accept honeycomb creaks.
- DPI micro-tuners: ten-unit adjustment and 0.7–2mm LOD steps.
- Complete-package ultralight buyers — 8K dongle and 16 dot skates in-box.
Who should skip it
- Palm grippers — even Pulsar's copy isn't about you.
- Lefties — left-only side buttons on a symmetrical shell.
- Battery-first shoppers; this class and polling ceiling trade hours for grams.

FAQ
43g or 45g — which number is real?
Both. Official spec: 43g ±2 with the included dot skates, 45g ±2 with regular full-size skates. Pulsar ships dot skates in the box precisely because chasing the headline number is their design language (CrazyLight). Swap back for glide feel.
What is the X2N shape vs the classic X2?
A ground-up shape, not a shrink: high hump + narrow waist, low-profile front, explicitly tuned for claw and relaxed-claw (official wording). The X2 family split by intent: X2V2 for neutral claw, X2N as the locked-in claw platform, X2H for the bigger palm-leaning hand.
Is 43g too light for stability?
For fingertip/claw, it is the sweet spot of the 2026 ultralight tier; palm players will find the hump support is what keeps it planted, not mass. Community notes the shell can feel hollow to some hands at this weight — the CrazyLight trade.
Does it need software?
No: DPI (10-step fine tune), polling, LOD and Turbo Mode all set via Pulsar's web driver or mouse-bottom buttons. The 8K receiver ships included — the headline polling rate needs no extra hardware.
Who should skip the X2N?
Palm-dominant grips (the narrow waist offers no side shelf), lefties (side buttons left-only), and anyone sensitive to hollow-feel shells at 43g. It is a purpose-built claw tool, and Pulsar markets it exactly that way.
