Found them on ALIBABA. They are scammers. Here's the dispute from Ali. Shenzhen XDX Industrial Co., Ltd. never made what they had promised. As it was said, we prepaid 30% first dates of june 2016. 70% were paid 31 oct. 2016. 1) Huge delay with production. We lost the summer season 2016. 5 month in production instead of stated in invoice max 45 days. They promised extra wheels and made only 6 packs for this huge delay. Too little! 2) More than half of the products (all 50 and 60 mm wheels) don't meet the sample standards (the shape is off axis, asymetrical, deformed) 3) Packing was not accurate. Stickers for 64 and 72 mm are pale. Need to remake. Some blisters broken. 4) SZXDX didn't want to treat us good. Didn't want to remake the wheels. Didn't want us to send faulty wheels to inspect. They only decided to remake the wheels after we made first dispute. 5) Now it's nearly 1 year after first payment. 3.5 months after they promised to remake the wheels. 6) Miranda (manager of SZXDX) said that they revise molds after month from promising to remake the wheels. Now she is silent for several months. Other manager Jacky states the same. 7) I suggested a common decision to only remake the wheels (no blister, no spacers), use my delivery company and pay the shipment. 8) Miranda said first of all that their factory is big so they couldn't produce faulty wheels. Said that it is expensive for them to remake this wheels. Bad service. No responsibilities. Hard to conversate. Miranda was very very rude with this. Never stayed in touch after the problem. She doesn't care. Never answer. 9) The factory in the face of Miranda is very rude. Not communicative. No updates for months. Don't want to lose another season. They are aware that it can kill my business. Still go for it. 10) Don't meet their certificates standards in terms of checking the quality and making it easy for clients to deal with them. (For example, ISO-9001-2008) I did everything possible that depended on me.
