Question: how does it do with more than one pc? I will likely be using 2 thinkpads simultaneously, with a dell laptop too (roommate) all on same coffee table.  Has anyone had any problems with the bluetooth device from other machines trying to pair with the mouse?  I will likely switch the mouse between my thinkpads.  thoughts anyone?
Document: Simply put, if you have a newer laptop, you likely have very few USB ports... Using a bluetooth mouse is simply the way to go, and this one is the right size to pair with a laptop. Not too big (for packing in the briefcase), not too small (feels good in your hand). It's an optical mouse with an on/off switch which is good for saving the battery. My only complaint is that from time to time it loses connection with the laptop.
Bought this for my new Dell XPS 12 (2-in-1 laptop/tablet), which has only two usb ports. Needed a bluetooth mouse so I wouldn't have to use up one of the TWO ports. Struggled for days trying to make the mouse work, and couldn't get it going despite uninstalling and re-installing the software twice. Frequently the computer would finally recognize it, and occasionally the mouse would even work - for about five seconds.
Looking for a wireless mouse with less bulky receiver. Hadn't tried a bluetooth device before, but thought I would give it a shot. Very happy with this device. Nice looking (blue), quality feel, no problem on surfaces I used to have trouble with (couch, leg, board room table, etc.). Followed simple instructions to pair the device with my laptop and it's worked great since.
I bought this product to replace a Logitech V270 bluetooth mouse. I was having problems maintaining connectivity with the V270 and reconnecting using the Logitech software was inconsistent. I found the V470 to be able to connect without the Logitech software using the bluetooth utility on my Dell XPSM1210 laptop, and the connection is more stable than was the V270. I have only 2 complaints with this purchase. The logitech software that came with the V470 mouse was older than the software that came with the V270.
I originally got this for travel with my netbook, but it replaced my everyday mouse. Perfectly comfortable, extremely long battery life. Found the default speed to be a bit quick, easily remedied in the settings.Be advised, my boyfriend has trouble using his on a surface below his Dell XPS M1530 laptop (ie laptop is on a table, and he is sitting back on the couch with the mouse), but that's a Dell bluetooth antenna issue - not Logitech's fault.
I just made the switch to the "dark side" by purchasing my first Macbook Pro. I decided that since there are only 2 USB ports I should look into getting a bluetooth mouse so I don't have to use up one of my ports for a mouse. I did a little research and read the reviews of the other bluetooth mice on Amazon and decided to go with this one. It comes with batteries and was easy to pair with my Macbook.
it is very easy to pair with any bluetooth enabled device, and i have played a few games with it, and i have always loved the way the m185 feels, and this fells almost exactly like it. the only thing is that  it is heavier, due to it using 2 AA's instead of the m185's 1 AA.
As other reviewers have mentioned, this device drops connection after about 2 minutes of use. It will not reconnect unless you remove the device in the Bluetooth device manager and re-add it. The connection is completely unreliable. The laptop I was trying to connect to is a brand new Samsung Series 9 system with the latest Bluetooth hardware and software. I'm very surprised (and disappointed) that this device does not work as expected considering that it and the laptop are both current models.
Was looking for a bluetooth mouse for my macbook pro and cost was a factor. The mac mouses were to expensive in my opinion. This mouse has had no connective problems and tracks great. Its just a mouse it should work correctly. I have the macbook on a tray table next to the couch and use the mouse on the couch because i'm laid up from a knee surgery and the mouse control is perfect. I would recommend this for anyone looking for a bluetooth mouse.
(I did not have this problem, however, with my Dell Latitude D630 laptop with integrated Bluetooth and running Windows XP. )Otherwise when paired with the iMac (which is the main reason I bought this mouse), it performed well and was roughly 2/3 the size of a regular mouse. The "pro" is that your hand won't tire as easily when compared to using a smaller mouse. The "con" is that you're hand will tire more quickly than using a full-sized mouse.
Answer: I asked the same question, for the same reason, over at the Logitech forum. Unfortunately, for security purposes, the mouse can only "mate" with one computer at a time, so you can't use the mouse with both laptops simulataneously. However, you can make a shortcut to the mouse's connection in the Bluetooth Manager and it's pretty easy to switch laptops by just pressing the little button under the mouse.
