I purchased a 105 7000 groupset from riding_is_life, Ebay, from china. As stated above, no original packaging, but everything was wrapped and packaged very well. Everything was in tip top, brand new condition with no issues. I ordered right at the beginning of the USA starting to react to Covid with restrictions. The set arrived sooner than expected, about 3 weeks IIRC. I have purchased numerous other bike components from various other Chinese and Taiwanese companies with no issues. The only time I had trouble was an order with Aliexpress. I waited a long time and finally canceled the order as it was never shipped. I then had to wait 78 days for the refund.
