Logitech V470 Bluetooth Cordless Laser Mouse for Notebooks (Blue) Top Quality

The mouse worked well, and paired easily with my Vista 64 laptop. It comes with Logitech's SetPoint software, but the mouse works fine without installing it if you are worried about software bloat slowing down your computer. The only need for installing the software would be if you want to do some non-standard mappings of the mouse buttons/wheel.
After using the mouse for a little over a year I had opportunity to put Logitech's warranty to the test recently, so here was my experience. My mouse died, and I went through the usual troubleshooting--replaced batteries, made sure the batteries worked in another device, made sure my computer's bluetooth could pair with other bluetooth devices. I discovered that I had lost my manual, so I went to look for one on the Logitech support web site. Couldn't find it. Sent an email to support asking where I could find it. They didn't tell me, but did open an incident and started asking a bunch of questions that I'd already answered in the original email. So I went through 2 weeks of back-and-forth emails with them trouble-shooting the problem. They finally decided it was just dead, but said they would replace it under warranty. My original hard-copy receipt had gone the way of the missing manual, so another week of back-and-forth ensued. They would only accept a .jpg or .pdf scan of the receipt so forwarding the email receipt wasn't acceptable. But when I scanned that email receipt and sent them a .jpg image of it, that was fine. A month after my first inquiry, I received a brand new mouse as replacement. End result: Support was a pain and not particularly helpful, but if you're willing to be patient and jump through all their hoops, they will honor their warranty.
I also have the Microsoft 5000 bluetooth mouse, so can give you some product comparison (although I haven't had the opportunity to put MS support to the test). The Logitech mouse is larger than the MS, although still smaller than a standard mouse, so if you like a larger mouse that might push you to the Logitech. The larger size also allows the Logitech to use AA batteries versus the MS's AAA batteries. This gives the Logitech longer between changing the batteries, although I haven't done specific metrics to give you hard numbers on the difference. For the most part, ease of use and functionality are the same. The MS has an additional side button for those who think having more buttons is better on a mouse. All-in-all, given a choice between the two I'd just buy whichever is cheaper. Get more detail about Logitech V470 Bluetooth Cordless Laser Mouse for Notebooks (Blue).
