Hi,
I bought this keyboard around 2008 for $29.00 AUD which was a lot more than the $10.00 range.
I think its also known as the "Evolution Stream" - Although I don't recall that been printed on the box.
Its rather weighty thanks to the steel plate backing.
The keys are supported by rubber dome scissor switches.
Its well built and has lasted.
I really liked this keyboard at the time even though I'm not much of a laptop fan.
I brought it out of storage with a clean up to give it a run.
