difference between umax 2010u and 1600u

[FrontlineWarrior]

What is the difference? I looked at the specs and I can't tell the difference. Does anyone have any idea?

BTW I have the 2010u and I'm pretty pleased with it, although it makes fart sounds and take a while, for $20 it was a great deal. Now someone I know wants the same deal, but the 2010u is sold out, and 1600u is selling for the same price.

What specs did you see? I've only seen the Astra 1600U even though my 2010U will arrive on Monday.
