The three golden rules of ordering from HobbyKing:
1) Never *EVER* order items that are back ordered.
2) Look for review/build threads on Wattflyer or RCGroups and look for pitfalls BEFORE you buy,
3) Expect an occasional DOA item and understand that the expensive overseas postage will prevent you from returning it.
Case in point for #3: I've ordered a total of five HobbyKing branded 60A ESC. One was faulty on arrival, but since the ones that work perform great and cost a fraction of non-HK stuff, so it's a considerable saving even counting the DOA unit.
Following those simple rules, I've really gotten a lot of enjoyment out of my HK products.
