I bought the M92 in October, arrived in 10 days (from Poland to South Italy). As far as I'm concerned everything went ok. I'm just sorry you found out
later firmware differences between the various devices according to the place of purchase. I thought that all the devices were equal and equally updated. Mine is a black pearl and I take this opportunity to urge developers Onyxboox.com to release more frequent updates. I will also try to give my contribution to this forum, although I have purchased elsewhere my M92 (always if the “black pearl” are welcome...
)
