Have to love that url.40 dollar shipping. A lot cheaper then the x30 but still 400 dollars seems like a lot. I guess once someone reliable tests it.. and takes it apart to identify components, test app and syncing, I would feel more confident.
I don’t think they have the x15 on that site I guess. Maybe it was too costly and the x30 makes more sense to produce.
Still, It’s like in that awkward price. If you have $400 to spend you probably have enough for a name brand light. If you are on a budget then $400 is probably too much and a noop or smatfarm looks more attractive.
