Summary: No more wires. Replaced Keyboard and 'Laser' Mouse at same time as both my old ones were a bit 'tired'. Both were 'plug and play', but it's possible older PC's may need the drivers downloaded first. Small niggle is I have large hands and the Mouse is quite small. Took some getting used to after my previous 'ergonomic' version. Would be a solid 5-stars except I couldn't find a larger version at the time of purchase so only 4-stars.
Summary: Superb mouse-wheel, for effortless hassle-free scrolling and clicking. The scroll-wheel on my Microsoft comfort mouse kept sticking and stalling, so I threw it out in disgust.The Logitech Mouse is perfectly designed for my hand: I don't know it's there, and keep endlessly clicking and scrolling with it. It's by far the best mouse I've ever had, is fab and fantastic value for money.
Summary: A good mouse with excellent functionality and can be turned off when mot in use so battery life is great. The only drawback is that it is heavy and a little draggy on some surfaces made worse by the drag.
Summary: After a couple of months this mouse developed a problem where a single click was converted to a double click making the use of the mouse a nightmare. It appears to be a relatively common problem and temporary solutions can be found on the web. However I just changed mabnufacturer of the mice I use.
Summary: I got this mouse for a great price and it does exactly what is required. It connects well and easily, is small and compact as well as being a good mouse. It is not particularly feature heavy but most people don't require this. The touch sensors work well on the mouse meaning that the battery is not run down when you're not using it.
