Your mk850 keyboard and mouse combo is a joke. My keyboard constantly loses connection, and quite honestly I want my money back. This is unacceptable, and the stupid radio frequency BS youall push as to why it keeps losing connection is also not true as I have this same set-up wit hthe same laptop at my office (this one is for my home office) and it never loses connection due to radio frequency. I would like for someone to reach out, and either directly fix the problem or tell me how you plan on refunding me my money. Thank you, Andrew
