If you are on the lookout for a new keyboard and mouse you should checkout the iClever wireless keyboard and mouse set. Priced at £32.99 (on Amazon) the set comes with a rechargeable keyboard, battery powered mouse and USB wireless receiver.
The keyboards and mouse connect up to a PC or Mac via a USB wireless receiver that does not require any special drivers, just plug it in, switch the keyboard on and you are ready to go.
They keyboard is slim and light but still very good for typing on. The keys have short amount of travel and it does not flex like many budget keyboards. iClever say you can get about 90 hours of use from a two hour charge and you charge it via an included Micro-USB cable. The mouse isn’t rechargeable, you have to provide your own pair of AAA batteries. I could spend plenty of time typing on the keyboard without any issues.
A nice feature is it has a full number pad which would be great for Excel users.
