It's legit, but you probably won't get the support you'd get from a seller such as estore or even spytec (to some degree)
If it actually works out of the box then what support do you need ?
For such low money, is it an issue really ?
You want cheap, get from China.
You want easy returns, get local and pay more.
You can't have both.
As long as dashcam works fine, you never have to deal with support.
This is pretty stable camera so shouldn't have issues like generic cheap dashcams.
If it is legit, I'm going to buy it asap.
