I did buy one of these adaptor recently listed on eBay. I don't want to be overly stressful while I see no evolution on my tracking for almost two weeks, but I feel I need to make some quick remarks that might help someone also buying.
Amedeo used the Ebay Delivery service, a ESUS* tracking (this is different from the Ebay Global Shipping Program), despite listing informing USPS International Priority. I buy stuff regularly from the US (including from Amedeo before), posted with USPS: it has good tracking and I can take care of customs clearing in advance and with a reasonable fee.
I don't buy when seller lists Ebays delivery/shipping, as there is conflict of interests by Ebay, and will most likely not protect actually buyer. There are numerous reports of tracking marked as "delivered", when its apparently not. Also, tracking is very strangely not available on any website...
Please see I don't want to raise any doubts as regards Amedeo himself, I bough from him before and would like o buy again!
But as it was myself alerting here about the availability of adapters, I'd feel bad not sharing/alerting this with anyone that might be interested in purchasing, recommending to try to get in contact with Amedeo to organize a different shipping method.
