A:AnswerYes! The product is called a Logitech Unifying receiver for mouse and keyboard. Much cheaper than having to buy the trackball all over again too. The person who stole my trackball while I was running sound at our last St. Patrick's day gig here in Michigan will need to buy one of these too. Thankfully Best Buy had a new trackball on sale, so it's all good.
A:AnswerNo. It uses the Logitech Unifying connector and uses software to connect your device to your usb receiver. It won't be recognized by another receiver.
A:AnswerI find that after about 18 months or so I start having issues with the left button. It will start double clicking or not clicking at all and so I go and get my new spare for the closet and add getting another one to my to do list
A:AnswerYes. It is actually a unifying receiver so if you have two wireless products (i.e., mouse and keyboard) you only need to sync one and thus eliminates the need for two receivers.
A:AnswerIt works with my Mac Mini running Catalina. You'll need a free USB port for the trackball's Bluetooth transmitter, but should hopefully be good otherwise.
A:Answeruse a capped pen or eraser side of a pencil and turn the unit over and push the trackball out through the hole on the bottom. Use a paper towel or napkin to clean the trackball surface then use a q=tip or your finger nail to clean off the white (YES THEY ARE WHITE) sensor pads where the trackball sits. Lastly, make sure the tracking sensor (clear-reddish window looking thingy) is wiped off and clear of debris. The whole process should take less then 60 secs.
A:AnswerThe M570 does come included with 1 AA battery! On normal daily use, you can get up to 18 months worth of battery life from 1 AA battery. Any AA battery will work as a replacement when needed, and Best Buy does sell AA batteries as well.
A:AnswerThis turns out to be a not-uncommon issue. It is possible to replace the micro switch inside the trackball, but you should only try this if you are experienced with un-soldering and soldering on a printed circuit board. It is pretty straightforward if you're comfortable with soldering. See this YouTube video for details: https://www.youtube.com/watch?v=xlzEmRnu4DQ
At least that will give you a clear idea about what you'd be getting into. As you will see, the micro switches themselves are sealed so you can't clean the contacts... you replace the whole switch.
Hope that helps!
