Tempted to buy one, the dual motor with extended battery is 4300 odd rmb.
The reviews say the remote blows though.
I have a benchwheel dual motor for +- 1yr already, warranty on that has been decent, they repaired once, although had to pay for battery swap at 11month mark as it was cutting out.
I love the benchwheel remote, it fits my hand well, the acton style one on the meibacc is crap (tried it before).
China they call it the Meibacc 美巴克 appears to be made for Raldi
Pretty sure that the changzhou factory guy is a reseller (Rex / Bisek), factory looks to be ez skates from in wuxi.

Build quality isn't great great, but looks like should be able to swap stuff out fairly easily, eg -> dual vesc + decent remote, albeit for extra $$
The battery looks easily removable, which is nice, as I've been wanting to take a board back home, and its difficult via air if battery > 100kw/hr...
