Quick Summary
The MK Purple Slush is a cheap nylon-housed linear with a fun colorway and a classic, full Cherry-style sound. As a plug-and-play switch it is fun and sounds good for the money, with a medium 50g press. The honest catch is reliability: enough users report double-registration and dropped keys developing over time that we cannot recommend it without a clear caveat. Buy it as a low-stakes, hand-lubed novelty rather than a switch for a board you depend on.
Specs and Feel
Purple Slush actuates at 50g and bottoms out at 65g, with 2.0mm of pre-travel and 4.0mm of total travel on a nickel-plated spring. The POM stem in a nylon housing produces the familiar deep, thocky nylon sound — its best quality. Stock smoothness is okay but not remarkable, and some springs ship slightly ping-y. The bigger issue is consistency over time: the recurring reports of switches starting to register twice after months of use point to a longevity problem rather than a feel problem, and that has to weigh on any recommendation. Stem wobble is average, and the colorway, while fun, does not perfectly match the Frozen Llama keycaps if that matters to you.
Tuning
This is a switch that genuinely benefits from a hand-lube. A thicker linear lube such as a 205-grade smooths the stroke and kills the spring ping that some units have, making for a distinctly nicer switch. Films, on the other hand, do little here — skip them and put the effort into lube. Tuning improves the feel, but be aware it cannot fix the underlying durability concerns, which are mechanical rather than cosmetic.
Verdict
Buy Purple Slush only as a cheap, fun, hand-lubed linear for a casual or secondary board where a flaky key here and there is not a problem. If you want a dependable budget switch from the same Frozen Llama series, the tactile MK Holy Llama is a far safer bet, and for a reliable budget linear sound the KTT Vanilla Ice Cream is the better buy. Skip Purple Slush for any daily driver you cannot afford to have double-clicking down the line.
Frequently asked
What do MK Purple Slush switches sound like?
They have that classic nylon-housed Cherry-style tone — a fuller, deeper thock — though some springs can be a touch ping-y stock.
Are there reliability concerns?
Yes, honestly. A number of users report double-registration and dropped keys developing after about a year, so longevity is the main reason for caution.
Will lube and films help?
Hand-lubing with a thicker linear lube noticeably improves the feel and quiets ping. Films make little difference here, so you can skip them.
