Beware of the scam! Ordered a device for 100 euros to Germany, it came from a Polish warehouse, the device didn't work and we opened dispute. The seller asked to return it to china, which costed a lot and asked to get the cheapest shipping label. We purchased a label from DHL for 50 euro and shipped it. The item got returned to us because of the battery and after submitting the appeal with all evidences possible we still got rejected. This way we lost 150 euros with aliexpress. What a scam. These Chinese goods became expensive and the service is still on the level it was decades ago.
