ZugGear DUROCK Switch Film 0.15mm HTV+PC Soft Double Layer (120pcs) Review (2026)

What this product actually is

This is a pack of 120 switch films from Durock, sold under the ZugGear listing, made for Cherry MX style mechanical keyboard switches. Each film is 0.15mm thick and built from two layers, an HTV matte layer that faces the bottom housing and a PC transparent layer that faces the top housing. The film sits between the two switch housing halves before they snap back together, closing up the small manufacturing gap that lets the top housing shift side to side. It ships as a flat sheet or tray of individual films with a blue base for grip, not as a tool, so nothing needs charging or assembling before use.

Who should buy this

This is for people who already own mechanical switches, whether stock or aftermarket, and notice a rattly or hollow feeling when they press keys near the edge of the stem. It suits keyboard hobbyists modding a hot-swap board, or anyone rebuilding a set of switches pulled from an old keyboard. It is not for someone who wants a plug and play upgrade, since every switch has to be opened by hand, the film placed, and the housing closed again. Skip it if your board uses non-MX style switches, since the film is sized for the Cherry MX footprint and compatible clones.

What the film changes in use

Adding a film reduces the wobble in the upper housing, which in turn firms up the way a switch feels when pressed off center and can quiet the faint rattle some switches have out of the box. Because the film sits between the housings rather than around the stem, it does not change actuation force or travel distance, so the typing feel stays close to stock, just tighter. The 120 count is enough to film a fair number of switches at once, useful for a compact or tenkeyless board with keys left over as spares, though a full size board with a numpad will use most or all of the pack.

Installation and what to expect

Filming switches means opening each one, which typically means prying the top housing off with a switch opener or a flat tool, placing the film flat over the bottom housing so it lines up with the switch's posts, then snapping the top housing back on. Tweezers make placing the thin film much easier and are worth having on hand even though they are not included. This is slow work per switch, so filming a full keyboard's worth of switches is a project measured in an hour or more, not minutes. Anyone who has never opened a switch before should expect a learning curve on the first few before the process becomes quick and repeatable.

Verdict and alternatives

For switches with loose or wobbly housings, this film is a low cost way to tighten them up and improve consistency across a full set, and the double layer HTV and PC design is a well regarded combination in the hobby. It will not help switches that already fit snugly, and it never changes actuation force, so anyone chasing a lighter or heavier keystroke should look at spring swaps instead. Competing kits from other switch film brands cover the same 0.15mm HTV and PC format at similar counts, so the choice mostly comes down to price and what tweezers or tools you already own for the job.
