Pros: price (only $20)

Cons: no

Pros: Compact, but fits my adult male hands well. The hyper scroll wheel is switchable, but in hyper mode is unbelievable. This mouse is a great bargain! I have started taking it to work to replace the junky one they provide. I will have to get a second one just to leave in my locker at work! It installed the adapter in Win XP in mere seconds - automatically. It works perfectly on my laptop in Win-7. It even works on 2mm thick plastic on the desk at work.

Cons: None.

Pros: The mouse is nice and small, and uses very little in the way of battery, the connection is strong and stable. Functional.

Cons: The hyper-scroll gets rid of the middle click, something that feels like a bad trade, but is all in all just a slight nuisance. However, the material in this feels cheap. Also, the back button has already broken (The button refuses to register when depressed around 60% of the time), which is just downright disappointing.

Pros: Rubber sides make a comfortable grip, forward and back button well positioned, buttons have nice feel, hyperscroll is well weighted and useful, tracks well on a variety of surfaces, receiver stores completely away inside the mouse

Cons: As pushing on the wheel switches from freescroll to stepped scroll there is no middle button, receiver is large in modern standards (my older Logitech has a receiver the size of a penny), top plastic is noticeably cheap and hollow - not up to expected Logitech standards

Other Thoughts: It is a good mouse for the price, I just wished Logitech had used a better quality plastic on top as it feels cheap. I really do miss the middle button, but Logitech's software is very flexible so I'm remapping horizontal scroll to the middle button. It is a worthy trade off for the hyperscroll whell.

Pros: Fast scrolling speeds, ease of use, 5 buttons and laser tracking . And a great price that tops it all. And shipping from newegg. super fast as usual

Cons: None.

Other Thoughts: More deals like this would be highly appreciated . :)

Pros: I do not game so this is just for a replacement of the Touch Pad on my laptop and it works very well.

Cons: None known.

Pros: Awesome texture, love the easy access to the usb transmitter. Fast scroll is a lot of fun and more useful then it seems. Love the small pouch it comes with too, quality stuff.

Cons: Having forward and backwards browsing buttons to the left of the index finger is a little weird, but looks ok.

Pros: Great look and range

Cons: a little small

Other Thoughts: totally worth twenty bucks!

Pros: Very nice overall mouse. Small in size, sleek design, works well.

Cons: No way to change the center click functionality.

Other Thoughts: I bought this entirely because GamerX93 said that with the SetPoint software the center click functionality could be obtained. This is not true at all. The center "click" is ALWAYS "Shift Scroll Modes" between regular scroll and hyper scroll. I have SetPoint 4.80b and Windows 7, the newest software to date, and trust me, there is no center click functionality. To me, a mouse is useless without the center button.

Pros: It works fine, right out of the box with no issues whatsoever. The scrolling is fast and the mouse is responsive. Its small and portable as it should be for a laptop mouse.

Cons: None so far.

Other Thoughts: I replaced another logitech mouse with this one...I like the five button mouses and the last one didn't have the extra buttons. I like the mouse a lot and would recommend it to anyone.
