Got my second one a couple of days back as the wife "borrowed" the first one and would nt give it back! My new one is a 9V red led model, branded iRobot, metal case bought from a UK eBay trader. It is a Rockchips model 128meg ram and the interface and performance is better than the first 5V red led rockchip so I think these latest ones are 3rd batch but now have red leds.
