I just tried with the Speedlink SL-6495-RBK to write this text - but the keyboard is not suitable. Blind 10-finger tap - that does not work; for the keys are arranged too small and inconvenient. But this device is not well done! It's a media keyboard for the lap. The Video Player control to click through the Internet, maybe entering an address or a search term - for this device is perfect! Small that it takes place well on the coffee table next to drinks and chips dish, but big enough that even Wurstfinger nor individual keys can take. And not too easy: you realize that one thing has in hand. Placed with mouse buttons on the left and right trackball is an operation without rest comfortably possible - in similar keyboards that have the mouse buttons directly above or below the pointer leadership that are not as fortunate. I also attached importance to the scroll wheel - was missing me at my previous Media Keyboard (MS Sharkoon W98 D,). The SL-6495-RBK keys are soft and already want to be pressed quite strongly. Their arrangement is used to: for example, there is no right shift key, the top-bracket key is for the far right. In the operation in darker environments it will be interesting: a lighting there is not, of course. The small shortcut keys at the top make a (probably unintended) Krumm-and-wrong impression; I find it quite funny, others like the disturbing, particularly in view of not just low price, allowing the expectation of a higher quality impression.
Last words for packing: each item - keyboard, dongle, battery - plugged in a rigid plastic shell: for out fiddling patience is already required.
