I needed a new keyboard when the built-in one on my laptop lost a few keys and there was replacement available. After looking around I decided to get a Bluetooth one to make it easy to setup without cables getting in the way or using up a precious USB port. I had previously had a Logitech diNovo desktop set, but did not like the feel of the keys. My desktop uses a Microsoft Keyboard so I decided to try the portable version. I have not been disappointed, the keys are light but not too light, and there is a gentle curve to the keys making it a joy to type on. The setup is fairly straight forward and the device was usable within a few minutes.
The numeric keyboard has a little case to protect it in transit, it would have been nice to have a case for the main keyboard as well, but this is not necessary as it fits nicely inside the bag alongside the laptop. I hardly ever use the numeric keyboard but at times it can be very handy.
