Do not buy from Lofree
I purchased a Lofree Flow 74 directly from Lofree. The typing experience was terrible right out of the box, because the keyboard goes into sleep mode every few minutes, and unlike other boards (such as Logi), it doesn't send the keystrokes that wake it up again to the computer, so you end up repeatedly typing half-words and having to backspace them out. Second problem, certain keys began repeating cooonstantly — more backspacing. Third problem, the keyboard eventually stopped waking from sleep at all, so it's now an expensive, beautifully made, piece of junk. Fourth and ultimate problem: Lofree has the worst return policy I've ever seen. You can only return the device within 30 days of purchase if it is unused and in its original packaging. That's the most aggressively user hostile return policy I've ever seen. Do not buy from Lofree.
