You will get a decent product for less but warranty is often not actionable (sending back to China is more than the price of new)
If you wanna be safe: buy the kit without the driver for a little less and then buy the driver from a local or regional distributor; the driver is the most likely thing to fail with damage to your property.
2nd: sometimes there are batches of shitty gear/boards: I'd suggest running things a bit softer than original spec. Get a 200w driver for a 240 kit. If it means you end up with too little wattage no biggie just buy another kit and another driver again from your region. Generally these kits are a little over powered for the spread they give: the 2 board kits are perfect at 200w for a 3x2 but generally sold for a 4x2 at 240w. The softer you run it the less problems with failing gear.
And why oh why try to get a china clone of a light that isn't even good to start with?
The QB clones work great, avoid spiderfarmer imho
