IKBC MF108 is total junk. Quit working after less than 5 months. It's worth the price of 5lb of aluminum at the scrap yard. Cheap Logitech or Microsoft wireless keyboards work forever without a glitch.
Selling such worthless junk is a nothing but a scam. Don't waste your money on this garbage. If anything goes wrong, good luck fixing it or get your money back, especially if you buy it at Massdrop.
