Since this is a bluetooth mouse, there is a little more setup involved than with a normal USB mouse. Open the System Preferences, and navigate to the Bluetooth pane. From there, click on Set Up New Device, and follow the on-screen instructions to pair the mouse with the computer. Make sure the mouse is on when the discovery phase is taking place, and you should be all set to use the mouse in a few minutes.

The biggest selling point to the Logitech V270 is the Bluetooth wireless connectivity. But that is not the only bright side to this mouse. For instance, the size is small enough to easily carry around, but also large enough to use full time. When comparing it to typical desktop mice, it is only slighter smaller. Even with my large hands, I can comfortably use it for hours on end.

The overall feel of this mouse if very solid. It seems like it could stand up to a lot of abuse, which is a very good trait for those constantly on the go. The buttons have a solid, low tension click; and the scroll wheel is stable. Nevertheless, Logitech has included a carrying case for the mouse which will help protect it in your laptop case.

As with any wireless mouse, there is a concern about batteries. According to Logitech (and various user experiences), this mouse will last about 6 months on a pair of AA alkaline batteries. If you choose to use Lithium batteries, it could likely last up to a year between changes. This is due to the smart battery technology which sleeps the mouse while inactive. And if you will be traveling, there is a power switch on the bottom of the mouse. Turning it off will make sure the mouse isn't activating if a button is accidently depressed.

The sleep mode of the mouse does have one downside. If you haven't used the mouse for a few minutes, it will take the computer a second after moving/clicking before it responds. However, the delay is normally so short, it is hardly noticeable (and not much different than the time it takes to locate the cursor on the screen with your eyes). I can live with the delay if it truly means longer battery life.

Speaking of battery life, there is a little red LED on the mouse which will start to blink when the battery charge falls below a certain level. This will ensure that you will never run out of juice when you need your mouse the most. The LED indicates about 10 days of life left, but I would assume the blinking light would get annoying so fast, you will change the batteries as soon as possible.

Being a wireless mouse means I just had to test how far away from the computer I could continue to use the mouse. I set the laptop on the floor, and slowly moved away, constantly moving the mouse around a magnified dock. I was able to get about 15 feet away before the cursor starting skipping around. That was with a direct, level line of sight. If there is an object between the mouse and the computer (say, a human body), then the range is reduced to 2-3 feet.

Finally, the optical sensor is rated at 1000 dpi, so it can be very precise. Because of this high dpi, the mouse moves very quickly across the screen. I had to turn the speed down near the bottom of the scale in the System Preferences to make it comfortable to use. At least this high dpi means that it is difficult to find a surface on which this mouse doesn't work; a good thing for anyone who travels.

I encountered no problems with the Logitech V270.

This mouse is exactly what the doctor ordered when it comes to travel. Small size (but not too small), and lack of wires opens your laptop bag for other accessories. I highly recommend this mouse to anyone with a laptop that features built-in Bluetooth.

Pros	Cons
No adapter need for computers with built-in Bluetooth High precision optical sensor Perfect size for travel or desktop use Smart battery management means the batteries last longer Power switch on bottom to conserve battery power when traveling Included carrying case keeps the mouse protected Battery indicator light lets you know when the battery needs to be changed	Only two buttons (and a scroll wheel) Takes a few seconds after waking the computer from sleep before the mouse is usable
