I see on their front page HK is hiring for their "customer service department" ! Yikes, talk about a revolving door.
I've ordered three times from them but never spent more than I could afford to loose and all of it were things like wire,heat shrink,glue,,etc... but have since found other companies with good CS for things like that. They do have some neat things that no one else has BUT they also have the chicom copies of many items. Not clones but the copies . They also have gray market items got through unscrupulous distributors and that really hurts the legit dealers. Some of their Turnigy lipos are good for the price so I'll give them that.
They don't care about loosing a customer after they have their money as they think there is one or two behind them waiting to take their place. That logic works for awhile but eventually they will not get as much repeat business.
