Beware of underperforming clones

As of May 2022 all non-Plus4 hardware are clones (we have stopped producing older versions since October 2020), many of which perform badly due to using lower quality or salvaged parts, and users have reported software/firmware incompatibility. See official store and look for V2 Plus4 versions only to avoid getting a bad clone.
