Logitech MX 1100 Cordless Laser Mouse

I bought this mouse to replace my Logitech G7 (Carbon Black) mouse. Since receiving it this morning, I've been very happy with this MX1100. I'll highlight a few things that made this mouse better than my old G7.Ergonomics:I can fully palm the mouse and all but my pinky finger can rest comfortable on the surface area of the mouse. I have large slender hands so I find that my pinky and fourth finger will stay tight together on the right edge of the mouse as I grip it. It would have been nice of the right slope could be extended for those of us with larger and longer hands.Buttons:Unlike my G7 which only had one thumb button, this mouse has three (one "hidden"). This is great for gaming as I usually use one for voice chat and have found a lack of a second problematic. I now use the second button as a grenade key and have not yet found a use for the stealth key.Update (1/12/2009): I've been using this mouse for long gaming sessions most days of the week for the past 3 weeks and so far have only used 15% of the two AA alkalines. At this rate, I figure it'll last me at least another 4 months before I even need to change out the batteries. Although the box rates it for 9 months battery life, heavy use of the mouse will probably reduce overall battery life down to 5-6 months instead.This is far better than putting a mouse into a charging cradle every day (like the MX1000 or MX Revolution).DPI Switch:Although this mouse only allows you to set two custom DPI settings, it is enough for most of my graphics, general, and gaming use. It's definitely not as nice as the five DPI setting ability of my old G7, but having a DPI switch with only two settings is still a good compromise.Hyper-Scroll/Micro-Gear Wheel:Unlike the MX Revolution, VX Revolution (and others with the same scroll wheel), this mouse has a button to switch between the indented/click-to-click feel and the smooth scroll feel. I find this much more reliable than clicking down the mouse wheel. Another plus is that I still have a middle mouse button unlike that of other Logitech mice with hyperfast scroll. The mouse wheel button is also far easier to press down than on my G7 which makes it now usable extra button my gaming sessions.Batteries:Unlike other battery powered mice, the MX1100 can run on one or two batteries (hence the same polarity for both batteries in the compartment). Unlike my G7 where 7-8 hours of gaming would drain the 900 mAh battery, the MX1100 can probably go for a full 248 days before needing a new pair of batteries (number taken from Logitech Setpoint 4.70 with Duracell batteries that came with mouse).Update (4/15/2009): The two included Duracell batteries (2180 mAh @ 1.5v) lasted from 12/20/2008 to 4/12/2009. That's a total of 103 days of usage (heavy gaming 4 out of 7 days with the rest of the time spent on graphic work, general use, and animation. There were also a few days where I've left the mouse on overnight, so the two included batteries could have lasted beyond 4 months (approximately 120 days). I've since replaced the batteries with cheap alkaline "super duty" cells from Walgreens. I only expect about two weeks of total battery life before they die. If you have the money, invest in some reputable alkalines or rechargeable Ni-MH cells (high capacity ones - 1800 mAh or greater). Definitely beats having to swap batteries on my old G7 (or plug it into a charger like the MX Revolution).Cost:Lastly, this mouse cost $25 less than my old G7 (~$65 compared to $100). The feature set is about the same (maybe better depending on viewpoint), but the lower price tag makes this a better deal and a great step-up for me from my G7.

This mouse lost 1 star on two counts:1. Cannot be used by ambidextrous/left handed people2. Is a tad heavy and lends to wrist fatigueI love the size and curvature of the mouse (as opposed to many really tiny mice nowadays). The design allows it to fit well in your hand. Unfortunately it does not come with a micro usb receiver, but that's usually not a problem if you are not using it on the go (I have it hooked up to my desktop).It works fine on most surfaces, but like most mice fails on glass and certain weird patterned surfaces. Uses 2 AA battery's that last about 4-5 months until they need replacement.The spin wheel switch allows for an easy toggle between free wheeling (goes endlessly and useful for long pages) and slotted wheeling (when you have to scroll 2-3 lines per notch).The mouse has 4 buttons (2 on the top rocker and 2 on the side). The side back button is very easy to handle, the front requires a bit of repositioning of the hand, but is not too much of a hassle. The top rockers are fairly useless unless you are a person who uses the mouse with 3 fingers on top (index for the top rocker + first button, middle for the scroll wheel and ring for the right). I barely use the top rockers so it doesn't seem to impede my use of the mouse.I've rarely seen the mouse act spotty and lose signal, but it has a decent range. For the desktop I have placed below my desk, which is about 2 ft away from where my mouse is placed, it works relatively well (its usually the battery dying when it starts to act wonky).The weight is just a tad bit more for my liking, but it is not bad at all. A little weight on the mouse adds for more smooth handling than an extremely light weight mouse.Overall this mouse has stood up to its 4 years of being badgered by my usage. Would definitely recommend this to any right handed person looking to buy a quality mouse.
