Question: Range I need about 15 feet of range from this device... Would that be a problem?
Document: What can I say, 6 months later, the original batteries are still working. This mouse gets daily use by the way. The Nano receiver is simply awesome. Just plug it in and forget it. Has great range, tested it from 15 feet away. Very smooth tracking, very responsive, heavy duty solid metal scroll wheel that can ratchet or free spin. Comes with decent software. Logitech continues to raise the bar.
I do wish it used one AA instead of those pesky AAA batteries though...3. No software required to use like a standard mouse in WindowsXP- there's no need to install software if you just want to use like a normal mouse on Windows. It just works.4. Unbelievable range- works at 30 feet. Use this little guy for presentations or take advantage of the small receiver & #3 to play a practical joke on your coworker ^_^5.
I thought that this might limit range, but the mouse works fine at 35 feet, at least. I set up the button behind the scroll wheel for a double-click button. I would MUCH rather have been able to define the wheel button for this, but it appears to only be a mechanical switch mechanism for the scroll mode (Hyper scroll/regular click). This is the ONLY thing I don't like about this mouse.
To be fair, this doesn't happen every time I LEFT CLICK, but enough it is really an issue. So, I guess, for me the limit for the useful life for me is 2 years. But given the usefulness of the device for the time that it worked, was a positive. Even after this problem, I would purchase another "nano" without hesitation, which is what I will be doing after writing this review.BTW:  My 2nd NANO is working just fine after a year or so.
This is the third Logitech VX Nano Cordless Laser Notebook Mouse that I have purchased. All of them are still in daily use and performing well. All three were purchased as gifts for college and college-bound students for use with their laptops/notebooks.This mouse has just enough weight to make it comfortable for protracted use. The shape design fits well for either hand (the three students mentioned above range in height from about 5 feet to 6 feet 1 inch tall).
The IBM USB is on the left hand side and the mouse is on the right, often about 4 feet away. While generally this works fine, on occasion I will have to press the mouse button a couple times to get the receiver to register a command. Again, this is not a problem when moving the mouse or moving the scroll wheel, only if I push the left or right button to send a command.
Apart from the obvious advantage of the tiny receiver which fits into a USB slot which both works very well and has amazing range, the coolest feature of this mouse is the wheel. Click the wheel and it works like most mouse wheels. Click it again and it becomes a free spinning fly wheel which allows the user to go through documents and web pages at blistering speed. I really didn't use the wheel features of mice before now but this device has changed this.
And if I have the mouse entirely on the left hand side of the laptop I can be 10 feet away and it works fine. There is some 'dead zone' apparently where I have occasional interference and only on button pushes! But fairly uncommon and easily corrected by moving the mouse a bit. * I admit to liking Logitech products. Their software occasionally leaves a bit to be desired. But I finally need to grouse about Logitech's apparent need to overly market themselves via their software.
i didn't expect anything else than perfect device for my notebook. logitech is proving it's high quality standard. mouse is small, but still good for comfortable work. but for people with big hands it could be a problem. i appreciate the protective pouch, it keeps my mouse without scratches and dust when i throw it to my backpack together with notebook.
The Nano is great! it's tiny, and for laptops, I would highly recommend it. It's short range though would make it problematic for desktops.
Answer: I just walked to the opposite side of my bed room and used it and it worked fine. That must be ... approx. 12 feet.
