I've seen this on sale in Shanghai, they are of course unbranded lights that are sold by a lot of different people - and like all unbranded lights, some of which claim to actually make them

- and you can buy the same thing from other sellers for a lot less.
What's inside them? Don't know for sure, but as they only have a very dim modelling lamp you can be sure that they won't have a fan, and buying ANY studio flash head that doesn't have a fan is taking a risk. This type of lamp typically only has one capacitor (or maybe 2) which means that the colours AND the flash energy will be all over the place, not only at differerent power settings but also from one pop to the next. Also, recycling times will be very slow. Without adequate capacitors, the power can only be adjusted by using a potentiometer, which has a disasterous affect on colour temperature.
For comparison, the Lencarta SmartFlash has 9 capacitors - and that's the cheapest in the Lencarta range...
And the body is made of very soft alloy (sometimes described as aircraft alluminium) because it's very cheap to make. Looks tough but... And very poor electical insulation obviously, something to think about with the very high voltages involved.
And it has a fixed reflector, which makes it impossible to get any modifiers except for the 'universal' ones, which tend to be very poor.
Oh, and the Lencarta is just £140 more for very similar kit contents, so nowhere near twice the price.
If you've made up your mind that you can live with this kit then fair enough, but best to shop around for a cheaper seller.
