I loved my microsoft mouse that I bought at JB HiFi December 2019 until less than 18 months later, the bluetooth has failed. I've changed the batteries 3 times, cleaned the base, which I do almost daily, but it keeps dropping our of reception. My microsoft laptop is 5cm away so signal is not the issue. Its out of warranty so I guess it's back to logitech? I hope my laptop doesn't fail on me too :(
