The Vin 4x4 v1 is discontinued now, and mine lost some edge magnets when I took it apart (I still have no clue how that happened), so for Christmas I got a Gan 460 M V2. The v1 is said to be terrible, but the V2 is soooooo much faster than my Vin 4x4, and I really see no problem with it (except for the price).
