In the last one and half years I ordered 16 times from DD. They are not perfect, but I never had a problem with them. If you take your time and search thoroughly, and use coupos, you can buy some stuff for less than on DX or others vendors.
I bought a cheap lighter from them and a 1$ offer thing in the checkout. Fastest shipping ever, item was great, I will order more for giving away. So in overall I had very good experience, however I see the scam part and I dont like it at all.
@rad -
How about buying more expensive items ? can't rip you off with an item worths a few dollars 
No need to "change" anything, just get few of these and you may use the same charger also when travelling in US..
BTW: I got the same light yesterday and the charger did undercharge the original battery to 4.12V (only). I'll try to confirm that with another battery some other day.
