I ordered my Matias Mini Quiet Pro on January 8th and have been waiting patiently since then. After hearing about some quality concerns from people who got the first batch (or two?) of Mini Quiet Pros, I was pretty worried. I just got mine today and I'm pleasantly surprised. The Matias Quiet switch is much quieter than the Cherry Brown switches I'm used to (even with o-rings) and the tactility is higher as well. The activation point is much better defined. The action actually reminds me a lot of a brand new top-quality scissor switch with a longer throw. However I expect the Matias to keep the same feel unlike scissor switches, which get mushy after their rubber domes quickly wear out.
My keys all line up just fine (with maybe only a little bit of variation), and have the same amount of wobble as any other Alps switch I've used (which really makes no difference during typing).
Here it is in front of my Keycool 84. It's much more substantial in size and is taller, though the keyboard portion is only half a key wider.
The plastic is very shiny and is a total fingerprint magnet. That and the fact that it only has two small rubber feet are my only real complaints.
Hi there!
