Phenomenal, With One Catch
This is a phenomenal mouse. Full stop. The only thing holding it back from being an easy top pick is the weight — everything else here is close to as good as it gets in this shape category.
Build Quality, Switches & Skates
Incredible build quality, incredible switches, incredible skates. Everything just oozes premium the moment you pick it up. The hot-swappable Kailh GX switches feel deliberate and consistent, and the hybrid PTFE skates glide the way you'd want a mouse at this price to glide. Nothing here feels like it was cost-cut to hit a price point.
Wired vs. Wireless
I prefer the wired version over the OP1w 4K V2 wireless model, purely because it's noticeably lighter — 49.5g wired versus 59.5g wireless. That's a real, feel-it-immediately gap, not a marginal one, and for a claw-grip shape like this, the extra 10 grams from the wireless internals works against the thing I like most about this mouse.
Cable
The cable doesn't really bother me. Endgame Gear's Flex Cord is soft enough that it stopped being something I think about within the first few sessions.
Colorway
I have the Dark Frost version and love the look of it. It stands out from the usual black/white options without looking gimmicky.
If You Already Own a V1
If you already own the original OP1 8K, this V2 isn't really worth upgrading for. The improvements here are real, but they're not large enough to justify replacing a mouse you're already happy with — this is much more compelling as a first OP1 than as an upgrade path.
Weight
Just wish it were lighter. At 49.5g it's not heavy by any means, but it's also not competing with the sub-30g claw-grip mice at the top of this category. Everything else about the shape and hardware here is strong enough that the weight is the one thing holding it back from a perfect score.
Pros
- Incredible build quality, switches, and skates — everything feels premium
- Wired version is meaningfully lighter than the OP1w 4K V2 wireless (49.5g vs. 59.5g)
- Hot-swappable Kailh GX switches and true 8,000Hz polling
- Dark Frost colorway looks excellent
- Cable is soft enough to be a non-issue
Cons
- Not competitive on weight with the lightest claw-grip mice in this category
- Not a compelling upgrade if you already own the original OP1 8K
- Wired only if you want the lighter, better-feeling version
Verdict
A phenomenal mouse held back by one thing: weight. Build quality, switches, and skates all punch above the price, and the wired version's weight advantage over its own wireless sibling makes the choice between them an easy one. If you don't already own a V1 and don't mind the cable, this is one of the more premium-feeling claw shapes we've tested.
