My DHL, China to US, is 3 days. Probably 12 boards this year and never missed. I send my finished product back to China (LOL) and that takes 4 days. I find that shipping over the weekend is a good practice. With FedEx, they will hold a box 50 miles away over the weekend in a distribution center.If you can get DHL delivery in 3-5 days, count yourself blessed.
Every time I've been forced to use DHL, it's more like 2-3 weeks.
