Pros: Perfect size and shape (other than the scroll wheel, see cons). My hands are average size and this fills my hand perfectly.

Convenient DPI switch button. Easy to press if you need to but hard to press by accident.

Cons: The scroll wheel is rounded on top. It gets uncomfortable after using for a while. It was also pretty stiff to start with but eventually it loosened up... maybe too much. Occasionally it will scroll up and down repeatedly without me even touching it. If I turn it a bit it will stop so it's not a big deal.

Wireless receiver is pretty big. It's not the mini one that the smaller Pro Fit has. Not a big deal for me.

Battery cover could be easier to remove.

1200 dpi is pretty low for gaming. It's not advertised as a gaming mouse though so I won't take points for that.

Other Thoughts: With a few minor changes this mouse could be fantastic. If both the DPI settings were doubled and the scroll wheel was flat this mouse would be the best wireless mouse I've ever seen.

Pros: light (if u like that), good button placement, pretty sensitive, high dpi, and micro receiver...the whole reason I bought it over others at this price.

Cons: light (because I absolutely hate that), the right click button also tends to stick and be unresponsive on occasion.

Other Thoughts: I've had it for a few weeks now and its not living up to my old lodgitech the only reason I upgraded to this, if you can call it that, was the micro receiver....point is if ur going to go this deep in money wise save up $10 and get a better lodgitech they seem to be the only really reliable mice

Pros: Been 6 month's and not one problem the off switch help's use this 12 hours a day.The batteries lasted 4 months of couse i forgot to turn it off several times.So you could get 5-6 months,I really like this mouse been flawless no cable.

Cons: The drivers are tricky one of my computers said no so i went to Filehippo under drivers in the microsoft mouse file that took care of that less than a minute.Filehippo has all the drivers and there free.

Other Thoughts: It's big but so am i very comfortable played Mass 2 and 3 ,Skyrim,C.D. BF. Great gaming mouse.I'ts a good mouse.Bummer the price went up.But a steal even at this price.

Pros: Massive, but comfortable. My wife uses this for her desktop PC and thinks it’s much more comfortable than half size models. 1200 dpi is switchable to 600dpi using button below scroll wheel. Very accurate and smooth moving cursor. Plugged it in and was ready to go in just a few seconds (Win 7).

Cons: No drivers or programs to control functions available. It uses the standard Microsoft HID compliant driver from 2006. What you have when you plug it in is what you get. Minimal information on-line about button functions. I found out about switchable dpi by trial and error.

Other Thoughts: I had to purchase locally because older Microsoft wireless mouse died and I needed replacement right away. Tried the newer Microsoft 5000 Blue Track but cursor movement was erratic and not very precise. This was second choice but turned out to be a winner. If you don’t mind lack of being able to program buttons, cursor or wheel, then this is a definite buy. My first priority is accuracy and smoothness of cursor movement and this is what makes this a 5 egg choice. If you want all the bells and whistles of programmability, then maybe this would rate 3 eggs for you.

Pros: 1200 dpi, smooth action, works great.

Cons: No custom drivers. Uses Microsofts HID Compliant driver from 2006. That driver prevents computers from going into Standby. Checked Kensington web site - nothing for this model - K72370.

Other Thoughts: Very large mouse. I have average size male hands and my index finger can barely reach the scroll wheel without lifting my hand.

Pros: -If you're looking for a full sized mouse because you have big hands or are just more comfortable with something under the palm then this mouse is probably a good fit for you. I find it to be very comfortable and have had no connectivity issues.

-I've been gaming with this mouse and find it to be quite capable.

Cons: -None yet

Other Thoughts: -I'd like to update this post in a few months with comments on the mouse's battery life and whatnot.

Pros: PRICE..Best wire less i've ever owned tried to hide it still work's put a towel over it still work's.Comes with 2 energizer batteries,off and on switch.Where your thumb rest there are small holes and a very soft feal very comfortable mouse.A lot of quality in this mouse for the price it's a.. STEAL...You do get your money's worth.

Cons: I.m 6'1 large hands it just fit's any one larger should have no problem.It is big.

Other Thoughts: I wish they made a smaller for you little people out there ..
