KAILH Low Profile Choc V2 Keystem DIY MX Switch (10pcs, Blue) Review (2026)

Fit for the job

This pack suits builders working on a low profile keyboard who want to try Kailh's Choc V2 platform, specifically its clicky Blue variant, before committing to a larger order. Choc V2 is a meaningful update from the original Choc line because it uses an MX-compatible cross stem rather than Kailh's own low profile stem shape, which matters a lot for keycap shopping since MX-stem compatible low profile keycap sets are far more available than Choc V1-specific ones. Ten switches is enough to test feel and confirm PCB compatibility but not enough for even a small keyboard, so this works best as a sampler or spare parts pack rather than a primary source for switches on a real build.

Features and specs

Choc V2 switches measure 15mm by 15mm, the same low profile footprint as the original Choc line, but with roughly 2.8mm of total travel and a cross-shaped MX-style stem instead of Kailh's proprietary Choc stem shape. The Blue designation in Kailh's Choc V2 lineup refers to a clicky switch, meaning it produces an audible click at the actuation point in addition to tactile feedback, similar in concept to a Cherry MX Blue but built for the shorter low profile travel distance. Clicky low profile switches like this one are less common than linear or tactile Choc options, since most low profile boards target quieter environments like offices, where full-height clicky switches are already discouraged.

Build and materials

As an official Kailh listing, these switches should match the consistent housing and stem materials Kailh uses across its Choc V2 catalog, built from the same nylon-based housings found in the rest of the line. The MX-compatible stem is the standout build feature here, since it is molded to the same cross shape as full-size MX switches despite the shorter overall switch height, letting low profile keycap makers design caps that mount the same way MX keycaps do. This compatibility engineering is the main reason Choc V2 has become popular among low profile keyboard designers compared to the original Choc stem shape.

Value for the price

Like other small Kailh sample packs, the per-switch price here is higher than buying a larger 30 or 45 piece pack of the same switch, so this listing works best as a way to confirm switch feel and stem compatibility before a bigger purchase rather than a cost-efficient way to source switches for a full build. Builders who already know they want Choc V2 Blue for their entire keyboard should compare the per-unit price against larger packs, since shipping costs get paid again when a second, larger order follows a small sample pack like this one.

How it compares

In mechkeeblab's low-profile switch guide this pack ranks near the bottom of the field, behind Choc V2 Brown tactile and Choc Red linear options that score higher, partly because clicky switches see less demand in the compact and travel keyboard market that low profile switches largely serve. It scores similarly to the Choc 1350 Brown pack also sold by Kailh, though the V2 stem's MX keycap compatibility is a real advantage over the older 1350 platform for anyone who wants more keycap choices down the line. The clicky sound profile remains the main limiting factor for broader appeal.
