Title: Pcper testing of rk-9000
Post by: bondonin on Tue, 26 November 2013, 21:07:04

http://www.pcper.com/reviews/General-Tech/Rosewill-Second-Generation-Mechanical-Keyboard-Review-RK-9000-RK-9000BR-RK-90-4

In the link above the new version of the rk-9000 seems to perform poorly in the accuracy test. Is the test too unfair and unrepresentative of real world use or is it something to keep in mind about the rk-9000?

I've never seen a review go that in-depth, however I have some doubts about their methods...

I seriously have never heard of this type of keyboard testing before.

Take it with a grain of salt

RK-9000 is not that bad of a board

This is pure  Quackery.... *********(http://www.cute-factor.com/images/smilies/onion/8dcf9699.gif)

using a straight edge does NOT guarantee actuating the keys simultaneously.

the keycaps are not perfectly molded..... the mounting plate is not perfectly flat, the pcb traces have minor differences in length...

The computer polling is also Never perfectly spaced..

add in User error..  using one's hand as testing equipment... biases for left and right preference...

.......

The way I read it, they weren't trying to press the keys down simultaneously but try to depress a bunch of keys in sequence very quickly using the edge of a card. Its odd that the old version did better in the testing.

Even if the test is too hard for real world usage, its surprising that the Razer did alot better than the rk-9000 v2.

the test done is too unscientific...
