Summary: Got this for my laptop for when I travel. Funny thing is that I've also started using it for my computer as well. Love the fact one can store the receiver inside the mouse and take it along with you.
Pros: Lightweight, laser, wireless, good feel
Cons: Wireless, but the reason is because it requires line of sight to transmit. As long as one uses a port hub on the desk and plug the receiver in, you're golden.
Summary: The Microsoft 5000 series wireless mouse I had would not let me play games unless I relocated the USB transmitter to the desktop with an extension cable. Otherwise the cursor would take a brief pause on its way to the weapon I was selecting. This is annoying in MS Word, but it's death in a video game. I'm not primarily a gamer, but sometimes it just didn't work unless I moved my off hand out of the way or something. This mouse has no such problem!
Cons: -Detents on scroll wheel (if you prefer a smooth scroll wheel). -Size? The following are not cons, I just needed more space for the review. I admit that I have not pushed the mouse to it's limits. My angle is that I just wanted a mouse without wires that worked well over the short distance between my computer on the floor and my mouse on the desktop. I don't have any comments on the transmitter being hard to remove because I haven't ever removed it. I haven't programm...
Summary: If you own the M305 model, this mouse is only slightly larger. It is NOT a full sized mouse. But then, I do own the M305 as well and wanted one with the unifying receiver, preferring a smaller mouse and the M505 fits the bill! M305: 2 1/4"W, 3 3/4"L, 1 1/2"H M505: 2 3/8"W, 4"L, 1 1/2"H For Linux users: If you have access to a Windows machine, you can configure extra Logitech devices that use the unifying receiver.
Pros: All Logitech mice glide well, but some better than others, this is one of them. On my cloth mouse pad this mouse slides very easily. As usual, the buttons are neither too light nor firm. The unifying nano-receiver is tiny and there is a place to store it inside the battery compartment. And not to be too girly about it, but I love the sparkle in the red body.
Cons: It doesn't do the dishes, laundry, vacuuming or wash windows.
Summary: The unifying receiver is great, just don't rough around with too much, since the black plastic cover could break off. Not a deal breaker or anything like that.
Pros: This is a very comfortable mouse to use. The batteries really will last surprisingly long. Mine has been beaten up pretty bad, yet it is holding up great. It has a sleep mode that it reverts to after ten or fifteen minutes, preserving the battery. Out wakes instantly with activity. Nothing fancy, no extra buttons, so very practical for those wanting a simple quality mouse.
Summary: This mouse is worth every penny, just for the money it will save you in batteries. Loved mine so much I bought 2 more: for my mom and for my wife.
Pros: +2 AAs have lasted more than a year, using for a few hours at a time 4-5 times a week. I even forget to turn it off and leave it jostling around in my bag for a day or two at a time. +Great Sensitivity +Small, but not as small as many tiny notebook mice +Tiny receiver that you never have to remove, but if you do, there's a compartment in the mouse to store it.
Pros: Excellent wireless mouse for the money. I bought the M505 instead of the M325 because it was slightly larger. Response is great, and I was able to get the back and forward button functionality after installing Logitech's Setpoint software.
