They show their U.S. warehouse as being at 17806 Main St. in Carson but if you look up that address on google maps it is in Gardena and has a different zip code than they are showing.
There are so many well-known reputable on-line sellers. The only reason to consider an unknown company is if they are offering a really cheap price and that to me is a big red flag that either the company is not legit and will steal your money, or the product is not legit and you're getting junk. I'm sure there are some exceptions but why take the risk to save a few bucks?
