The seller sells a industrial trash, the pan was made crooked through the error of producing process. Indeed, these kinds of things can not be sold in China. So they tried to sell it to the foreigners. I opened dispute, the result is that I get half of the refund, or I should return the item at my own cost.I think this is not fair, they don't treat this issue according to the trade regulation, rather politically. This shop is BABK Super 520 Store. Don't buy anything from this shop, the seller is selling damaged goods intentedly.Furthermore, the sellers on Aliexpress have hacked my feedback systems several times, even if the Aliexpress have repaired it, still you can see this is not secure page.And there are many falsified 5 stars feedbacks, which edited in perfect English language with series of pictures one after another.So their sellers can manipulate the feedback system without their notice. My experien is thus that I will never buy things from Aliexpress which is over 200 Euro, if there is a problem, I will not loose too much money.
