The QPAD MK-85 has all the right features, and you get to choose what key switches goes in it. The only possible reason not to like it is its quite extreme price of €149.90. This is €30 more than the now elderly MK-80 keyboard which has exactly the same features as the MK-85 just without drivers and a few other minor things. The build quality and finish of the product is still top-notch as you would expect from a company like QPAD, however, even that is still not enough to justify the price.
It is good to see a mechanical keyboard that includes some of the everyday convenience features available on pretty much any business keyboard, the inclusion of both USB ports and audio pass-through is definitely a nice touch.
With QPAD you get the choice of key mechanism, which is nice. Finally someone is building keyboards that people want instead of just pushing one type of key mechanisms. People have varying needs and preferences when it comes to key mechanisms and it is great to see a product catering to all people who are serious about typing, gaming or both. Personally I prefer the Cherry MX Brown keys, but each his own.

QPAD's build quality and design is definitely at the top of the pack. The MK-85 keyboard succeeds in incorporating a lot of nice to have features and has a good driver suite to boot. Whether the keyboard is worth the asking price depends somewhat on whether you have use for the added features and want a keyboard that has soft-touch finish.
