I was recently in a group buy along with around 2000 other guys around the world.
The product shipped from Banggood as they are equipped to handle such volume, but here come the "funny" thing.
Shipping and in particular tracking ( no lipo batteries ) was the most weird thing i have ever seen, i could not get my tracking number to work before i found some small Thai shipping company.
And even then it took the better part of 3 weeks for my item to get up here ( no customs delay here at least )
I have never had a Banggood parcel take that route before, normally its just regular mail out of China or HK
And the other guys and not least Americans had to jump thru some hoops to figure out where their parcel was, something like going to some half hidden Fed ex page, enter your tracking number there, that then generated another number you could go to another place ( US postal i think ) and paste that new number and then you could see your parcel.
By now after years of practice i have come to the convolution that after buying something in China, you are best off forgetting all about it, as most other options will just lead to aggravation.
At least i am not my friend, he is spinning around himself and screaming at his computer monitor, and that's just waiting for a parcel sent by mail from within Denmark.
