Have had good success with items from the UK and EU, have ordered from Rotagrip without problems. I rarely buy anything direct from China/HK these days, have had more problems the last year with very long shipping times, items not showing up or arriving broken. As others have mentioned there are some US distribution centers for items coming from China. As of some recently items show a US location f(like eBay) for the vendor, but items are shipped through DHL ecommerce and seems to be no tracking information for a week and then get delivered by USPS. It may be that the are still shipped by air from China (based on the packaging) and are then routed to the USPS for delivery. Example is below, but still quicker than buying from Chinese mainland vendors. I use to get power supplies direct from Taiwan which arrived within a week by DHL air. Other than a one or two items that I occasionally need these days, I no longer purchase items from Asia. I have also noticed significant increases in the cost of some items (like power resistors for braking), I now purchase these from Mouser and DigiKey for not much more and much better quality.
Also beware that there are numerous Amazon vendors with common US company names like Merlintools that ship from China and may take a month to arrive or longer. You often miss the shipping information and there is no information as to the vendors location or where it is shipped form.
