WHAT DOES WIRELESS MOUSE/ GREEN & BLACK MEAN?

4GHz and 210 hrs on Bluetooth; USB-C charging is via a furnished paracord cable. The 1 annoyance is that there is no place to insert the two.4GHz wireless dongle into your mouse itself, earning this much better for use in your own home than on the run. The burden, shape, Make high quality and sensor are all very good, so the Bolt warrants a advice.
