My items have all been related to RC aircraft - micro multicopters, spare parts, batteries and the appropriate chargers. It's interesting that they came from four different places, New York, China, Netherlands, and Sweden. Apparently they ship from wherever is closest and has the item. Everything arrived and works quite well and arrived pretty much in the time I'd expect or sooner (As in the case of the one from New York.)
I'd recommend that you take a look at them since the prices are very good. Just use good sense and check things well because you might find the same thing listed at different prices, Also you good judgement when making any expensive purchases because I've seen that customer service from many places in China to be somewhat of a problem.
