Hello Jetball. The M705 and K520 use our Unifying technology, so any other unifying mouse or keyboard can be paired up with the same USB receiver. To pair them, use our Unifying program found here: https://support.logi.com/hc/en-us/articles/360025297913
It won't go 40ft. Look at the Logitech presentation mice with laser pointer. I have one and it works perfectly. Check the specs before you purchase. Logitech will be able to chat with you on the best solution for you.
As best as I can tell I was able to go about 15 feet in my apartment. That is with walls and very congested wifi signals everywhere. If you are looking to use this in a boardroom or something like that where it would be more line of site with no walls I am confident you will get a longer distance, just not sure about 40 feet.
It can track speeds up to 3500 DPI! I have read on other sites, 1,000? If your a big gamer then you would want a higher speed! BUT, if your just a dabbler, like me, it's fine! It's ergonomic and solid and a good buy!
Hello Kenneth, the M705 mouse works exceptionally well with a Chromebook. The M705 works across all platforms and will respond and react the same way. Have a great day.
I read a review on the M705 wireless mouse. The article talked about the nice warranty available, but only if you purchase from an authorized supplier of Logitech products. Best Buy was recommended as an authorized dealer.
Best Buy sells many Logitech products, and their return/exchange policy covers all products they sell, including Logitech. So I think the "authorized dealer" issue is not really relevant.
