To be honest, I don't see the point. It cost more than an RX200, it's larger than the RX200, and has less features (lower power limits in TC, and no SS mode, really?), and the fact there's no ventilation is a No-No.
It would seem that Kangside is just a cheap "cloning" company, as you can see all their mods are poor copies, or should I say they were "inspired" by other mods by well known manufacturers. They have a version of the Reuleaux, the Sig100, the IPV4, the IPV D2, the Hohm Wrecker, iSticks, etc. All of their mods look inferior to their "sister" mods, and end up lacking features too.
So the fact that it's lacking safety features, firmware features, is of inferior quality materials, and costs more than the original......................that's a big ole "NOPE" from me.
