Very poor product indeed. Well, the concept of it is fantastic and would be perfect for use in the lounge. Unfortunately the performance and usability is what brings it down. So bad that I couldn't justify keeping the product.
I've had Bluetooth keyboards in the past, and still use one that I've had for a good 5 years now. Never had an issue with it. This one though, has the worst connection/range I've experienced. Within 1metre of the computer it was alright, beyond this it just got worse and worse. Delayed response, sometimes even no response at all. You can press a key and it would send a signal for multiple key presses. I paired my other Bluetooth keyboard to the receiver dongle that is packaged with this product and it worked fine from a distance of about 5 metres with walls in between. I can only assume there is some sort of major issue with the Bluetooth bit in the keyboard.
Another problem I experienced, when you choose to rotate the trackpad (another useful concept) the performance dropped and mouse cursor movement became laggy again, even from very short distances.
Finally, the battery life seemed to be pretty poor. I left the keyboard turned on, but not used and it lasted less than 3 days. The Logitech dinovo edge that I have will last me well over a month turned on constantly AND being used on a daily basis.
In summary, with serious performance improvements this has the potential to be a really good product. At the moment though it is just too flawed to be useful to anybody.
