If i understand what I've read about it correctly, it's a scissor switch board. If your not familiar with them, read up on them.
Most keyboard aficionados rate them above cheapo rubber domes, but nowhere near buckling spring, ALPS, Topre, or Cherry mechanicals. Many laptops are using scissor switches, so expect the feel of the keyboard to be similar to a Dell, Gateway, HP, or other big name laptop, ie not awful, but low profile = early bottoming out. It's fine for some, inexcusable for others.
If you've read an advertisement or review that just says "mechanical keyswitch" then technically I suppose its right (but then again, a rubber dome is mechanically depressed to contact the membrane / pcb, making it just as mechanical as any other switch, but i digress into semantics).
Don't expect to find any new board with sought after mechanical keyswitch for $30, especially a USB board with a built-in USB hub. As long as the cheaper to manufacture rubber dome boards are beating the dung out of mechanical boards in sales, it will remain a niche market, and as such mechanicals will demand much higher prices. Maybe one day we'll see something along the lines of Cherry increasing its presence in the US market with lots of blue, clear, black, brown, and red switch boards available at your local big box retailer, but I wouldn't hold my breath.
In any case, I'm sure that it kicks the snot out of any logitech mooshboards, and at $30, that does mean something.
