Right now, with the problems in China, ordering is Chinese Roulette. Since China is going to, or is trying to ban the shipment of Li-ion batteries, the whole thing is a total mess. Seems like they are having their own internal problems deciding how to manage it, so it's a nightmare. If they do manage to stop shipment of all rechargeable Li-ion like 18650, then the impact would be huge. I think that is what some of the problem is. Orders are being refused by Chinese customs (outgoing) and being sent back to vendors. If the package states "flashlight" on the customs form, some will go back to the vendor, because the customs agent is assuming that the flashlight has a Li-ion battery in it and some will ship, cause the customs agent didn't look, care or know.
As I say, it's a total mess. I am glad I only order components, like drivers and reflectors, but that may soon also be an issue. The times they are a changing.
It may not be DX's fault, but no matter what, if you can't get your item in 45 days, you need to file a claim for a refund. If you choose to wait for months, then you will loose your money. Do it whatever way you want, but once you go past 45 days, your money is gone for good. Doesn't matter if it's DX or any vendor, it's gone for good and if China post will not accept the package for shipment, then it will never get to you.
See, this Li-ion is dangerous thing, is becomming worldwide. Unfortunately, governments will mess it up totally, allowing one type of Li-ion to ship and another type not to ship and the customs agents will be left to their own devices in the field. It will be like any other regulation, full of holes and a big rat's nest.
I think that since there's been more "accidents" with recharging Li-ion in the military (where it gets noticed more), that it is bringing the Li-ion thing to a head. If some people with power decide that Li-ion is unsafe (as they have), then it will cause a wave around the world, and it is starting to. It's just misplaced so far, because the target is not all Li-ion, but only a few select types.
This is all just my personal opinion, from what I read, so take it for what it is, just opinion.
