Having tried various keyboards with various types of switches, I must confess that for typing on, the Cherry Browns are my favourites - hence the choice of this keyboard, which looks fantatstic and is great to type on. But I have same issue as Phyllis in her review - when you type on it (or even just tap the side of the case firmly) there's a curious ringing sound like a distant church bell - with a frequency of about 580Hz if anyone's interested. The quicker you go, the louder the noise becomes. It is definitely not the mechanical switches makign the noise, but seems to be emanating from something inside the keyboard that is underdamped. For £175, I think this is poor, as it is very distracting. When I get a moment I will have a delve underneath to see if I can see what is making the noise, but this is something I think Keyboard Company would do well to raise with Varmilo - it's just not acceptable at this price point. Usual excellent service from Keyboard Co, by the way, delivered quickly and with no hassle. So 5 stars for Keyboard Co, but only 2 for the keyboard, which looks great, is excellent to type on but makes a very irritating noise while you do so.
