Microsoft Wireless Mouse 1850

Very poor keyboard – The mouse battery goes flat after only 2-3 weeks of light use. And it is very difficult to replace it as the mouse compartment is so tight. Some keys on the keyboard occasionally miss and have to be pressed again harder, especially the space bar. A very poor product. Don't buy.

Can't get any cheaper than this... Hmm... maybe you can – After buying a Convair air-conditioning unit and a Lenovo Yoga 310 earlier, I just had to go buy a mouse due to some issues with laptop from the Good Guys. Uses 1x AA battery and a USB receiver, very straight forward and will do the trick so it's a no frills type of input device for this amount of money. Feels cheap and the plastic shroud in in my hands feels like I can easily crush it to bits.
