I have and it was really wonderful.
There will be times when things don't appear, and China has been a let down for me with two items.Having said that they ship thousands, so one or two have to go missing....
I bought American, and sent it also to a place in America, that was awesome.
As I live in Australia.
On the whole, maybe 5% may not make it...but you then tell the seller, they are happy to re-send.
There is no use being scared to use this service, it does work very well.
