Frequently Asked Questions (FAQs) about Mercury K Keyboards

Q: Are the GravaStar Mercury K keyboards available in the German QWERTZ layout?

Yes, absolutely! The most popular models and color variants of the K1 Pro, K1, and K1 Lite are natively available in the German QWERTZ layout (ISO-DE). So you don't have to adjust, and you have full access to umlauts (Ä, Ö, Ü). When choosing a model, simply look for the addition [ISO Layout] on the product page.

Q: What does "Gasket-Mount" mean, and what does the keyboard sound like?

In a Gasket-Mount construction, the keyboard plate is not rigidly screwed to the case but rather floats on dampening elements. In combination with our multi-layer foam filling, this absorbs metallic vibrations. This creates an extremely satisfying, deep, and rich sound ("Thocky") as well as a springy, creamy typing feel that's easy on your joints.

Q: Can I replace the switches on the K-series myself?

Yes! The entire Mercury K-series features a first-class hot-swap PCB. You can easily replace the mechanical 3-pin or 5-pin switches at any time without soldering, to perfectly adapt the typing feel or sound to your preferences.

Q: How long does the K1 Pro battery last in wireless mode?

The flagship K1 Pro is equipped with a massive 8000 mAh battery. Even with RGB lighting activated, it offers you enduring performance for epic gaming sessions without constantly having to reach for the charging cable.
