Rating: - Great addition to my computer
I've always liked the idea of a cordless mouse, but the one my parents used made me nervous about buying one. But this mouse has worked wonderfully. No cord adds a level of convenience that I've never had before. Other cordless mouse I've used went through batteries in a matter of days, but not this one. The battery life is long. It has a elegant, sleek design, so it looks great on your desk. This is my first optical mouse and I can't see ever going back. No ball to clean and I've found that the movements of the cursor are just as smooth as my old mouse, maybe even smoother (and I've had no problems on a black surface). The only fault I have found so far is the wheel which seems to move the screen in too-large-chunks. But I think this mouse is great.
Rating: - Best pointing device I've ever used
I've used so many different kinds of pointing devices (mice and trackballs) I can't count them. I've finally found the perfect device, this Logitech cordless optical mouse. I actually have two of them, one for work and one for home. I also own the first Logitech cordless optical mouse that came out for right handers, but gave it to my wife when this one came out, since I am left handed. I have not at all experienced the problem a previous reviewer had in the mouse being unable to move the pointer quickly and can only assume he had a defective unit. I introduced this mouse at work a few weeks ago, and everyone who uses it realizes that they need one too, and I notice it popping up on people's desks everywhere. It is so convenient if you're left handed, because almost everyone is right-handed and they come over to show me something and can simply pick it up and move it to the other side without the cord interfering with the movement. I have positioned the radio receiver behind my monitor where you can't even see it! And of course optical is the only way to go: it is incredibly precise and smooth. A fresh pair of alkaline AA batteries lasted three months. I replaced them with a pair of lithiums and I expect them to last a year! Imagine that!
Rating: - Great for beginners, but sometimes newer isn't better
Well, I really can't say anything bad about Logitech. They made my Quickcam Traveler, and it works perfectly. They made this new mouse, and it works almost perfectly. Yes, almost. Let's go through this one feature at a time...1) Cordless... Very nice! You leave a weird-looking receiver on your desk (They say it has to be placed away from electronic devices, but I've tried it on top of the monitor without problems), and you no longer have to worry about wires. I've gotten it to work perfectly at a distance of about 10-15 feet, but after that it starts to respond a bit oddly. Of course, from that distance, I can't read anything on the screen, so who cares? 2) USB... Works well. Just as well as a PS/2 mouse. So why not just use the PS/2 port? Well, they provide an adapter to do just that. I'm using the USB port... Why? Because I hooked up TWO mice at once. This one and my old MS wheel-mouse. They both work the same cursor, but I can pick and choose which one to use when. 3) Optical. BAD IDEA. Yes, you lose the problems that come with a ball, but no one seems to realize that with the right mousepad a ball mouse is just fine. Get a nice leather mousepad and you won't have to clean the rollers ever again. The optics don't respond fast enough, especially when I want to jerk the cursor to a button across the screen (Or do a quick 180 in CounterStrike). It assumes you picked up the mouse, and doesn't move the cursor at all. Bottom line: Pros - Use it anywhere with out worrying about the wire - Wheel and L/R buttons respond well - Don't have to clean the ball/rollers - USB - Hook up 2 mice at once, and use a ball mouse where this fails Cons - Optics don't read sudden movements (Common in gaming) - Wheel button is a bit stiff (Harder to press than most older mice) - DOES NOT WORK ON BLACK SURFACES! (Sorry, no black desks or pads) - Wastes a USB port when PS/2 is just fine Bottom Line It's nice to lose the wire, but if you're a power-user, avoid optical mice entirely!
