Quoted from mavantix:
I bought a new v5 on this last run, when that comes in, I'll have a v2 (I think) edition for sale... it might be a v3. Really not sure.
easiest way to tell what version of Snackbar you have is the number of screw heads on the top and lighting and decals changed a little with each version:
v1 - (105 units) - el wire, 5 screw heads on top and dome
v2 - (111 units) - acrylic light blades 9 (more square edges), 2 screw heads on top and dome
v3 - (51 units with 5 being "custom" mods with + 1 never circulated is a failed concept + 7 DIY "kustom" kits sent out named) - resin light blades (more curved edges), 1 screw on front face, 1st edition with sign
v4 - (16 units + 1 DIY embossed "SnackBar v4" kit sent out) - resin light blades (more curved edges), no screws on top or front, 2nd edition with same sign - magnet hold down, will have "SnackBar v4" engraved in the underside
v5 - (50ish units to be finalised) - resin light blades (more curved edges), no screws on top or front, 3rd edition with same sign - magnet hold down, SS plate is dedicated to the magnets with M3 holes not M4 holes - will have v5 engraved in the under side of the top
Note: also I did a retro fit kit so the sign can be used on the v1 and v2 - this replaces the dome in the top.
In my v5 manual I detail the differences so people can identify what version they locate in the future. Here is an extract explaining the base plate differences.
hope it helps
