I could go on for awhile about HK. At first all was good. Then things went south real quick. I ordered a 4S 4500MAH battery that took 16 days to arrive from Lakewood warehouse. Put it on charger about a week later and HELLO! Dead cell. No way to get hold of anyone. The 30day warranty arrived so I bit the bullet on that one! But, the final straw was opening the US East Coast warehouse. I live in AL so I figured I would finally save on HK's high shipping prices. I ordered 4 small items that totaled $11 and weighed 14 ozs. Not much choice as to how to ship. The shipping came to $7.48 from AR to AL! I spend quite a bit of money shopping on line and never have I seen shipping charges in the 60% range vs cost on these type of items. No hazmat on that order by the way. I was warned by members of my rc club, but I didn't listen.
