First Impressions
This is a bigger mouse than the standard Superlight 2, and based on how much this site favors compact shapes, that size should have worked against it. It doesn't. The asymmetrical shape feels noticeably better in hand than the standard Superlight 2's more generic profile, and it doesn't carry anywhere near the restrictive feeling I braced for from a bigger hump.
Shape & Ergonomics
The ergonomic, right-hand-only shape is the whole story here. Despite being larger than the standard Superlight, the hump doesn't box my hand in the way I expected going in — if anything, it's the opposite. Microadjustments are noticeably easier on this shape than on the standard Superlight 2, which is exactly the kind of fine control that's hard to put a number on but immediately obvious in hand.
Skates
Somehow, these feel a tiny bit better than the standard Superlight 2's skates — which isn't a category Logitech usually wins on this site. I don't have a clean explanation for why. It's a small difference, but a real one.
Coating
Same coating as the rest of the Superlight 2 lineup, which continues to be one of the best around on this site. No surprises here, and none needed.
Scroll Wheel
No issues. That's worth calling out specifically given the standard Superlight 2's scroll wheel has a real failure history on this site — this unit hasn't shown any sign of that.
Pros
- Bigger than the standard Superlight 2, but feels far less restrictive
- Noticeably easier microadjustments than the standard Superlight 2
- Skates feel like a small step up from the standard Superlight 2
- Same excellent coating as the rest of the Superlight 2 lineup
- No scroll wheel issues, unlike the standard Superlight 2's failure history
Cons
- Right-hand-only asymmetrical shape won't suit left-handed or ambidextrous preferences
- Still doesn't have Logitech's HITS click tech
- Premium price at $159.99
Verdict
This needs the HITS treatment, and it would be amazing. Logitech already proved with the G PRO X2 SUPERSTRIKE that haptic switches are the future — give this shape that click tech and it stops being one of the best shapes on this site and becomes something closer to untouchable. As it stands, this is already one of the most comfortable, easiest-to-control shapes I've used, skates and scroll wheel included.
