Logitech M325 Wireless Mouse: This mouse's scroll wheel is ribbed, and the round, contoured body comes with rubber grips, so it's comfortable to use with your left or right hand.
A: The part you're referring to is called a "receiver" or "nano-receiver". You can purchase it separately, just Google "Logitech Unifying USB Receiver" and make sure what you pick is specified for your mouse model.
Q: Is green light supposed to be solid or go off after a few seconds?
A: The green light doesn't stay on, it does that to conserve battery power. When you've downloaded the software, you can program one of the buttons to show the battery level. Also, anytime it's been sitting long enough to go to sleep it will show the battery level when you wake it up. Of course like you said when you turn it off and turn it back on the light turns on to show you the battery level and then turns itself back off. The battery indicator ALSO works when you unplug it from the cord while it's on. I hope I'm clear enough to be understood in my answer :) Have fun!
Q: what does flashing red light mean?
A: Time to replace the battery/batteries.
Q: work with windows 10 desktop pc ?
A: Yes it does
A: Did you check a space where the battery is? There is a USB receiver, so you can put it in your computer.
Q: Is it possible to use more than one M325?
A: The device is normally paired to the unified receiver so no need to worry about cross talk. I use multiple Logitech devices in the same office with unified receivers and none on them pick up what the other is doing (they are 4ft apart). Just as an FYI, there is a unified tool/software from Logitech (http://support.logitech.com/software/unifying) that helps you sync or pair your device with another receiver. It will also show the paired devices if you really want to see what device you USB receiver is set to use.
Q: Will this mouse work with an Apple iMac?
A: Yes, this product is compatible with Windows, Mac and Linux operating systems.
Q: Is this a mini or regular sized mouse? I want to use it with a desktop not a laptop.
A: The dimensions are 3.7 x 2.2 x 1.5 inches.
