Oh ok, I get it. It sucks that it will take so long because I'm used to getting things in about 2 to 3 days from US companies.
If you are used to buy from american companies, you are used to pay a lot more than you have to do at KD og DX. 
Things are a little slow in coming though, so what you gonna do is to order one item at a time with a day or two in between.
The postage is free so you dont need to have it all sent in one package.
Then you can sit back and let your postman deliver a steady stream of nice and cheap quality products. 
That is the price we have to pay to get cheap flashlights. Maybe I should put in an order at KD and SB so I get flashlights once a week or so. Hmmmm....
My DX lights finally came in today. 
It's been 2 weeks and 2 days since I ordered them which isn't bad I guess but for me that was a lifetime of waiting. The first thing I noticed that I didn't like was how all 5 flashlights were sent in a paded envelope with a little bubble wrap around each one. I can see how easily items can be damaged during it's long trip to the US.
That is probably what happened to the TANK007-E07. I put a battery into it and nothing. I tried several fully charged AA batteries and still nothing. The other 4 worked just fine so I guess 4 out of 5 isn't too bad right?
There really is very little in it to go wrong. I had one of mine keel over but I managed to get it back to life. Most of the troubleshooting steps in that thread don't really apply as this light is rather different. First thing to try is to unscrew the head and attach a cell to it (well hold onto a cell on top of it) with the + contacting the positive contact on the head. Run a bit of wire from the battery - to the brass and see if you get any light. If you do, then it is a switch issue. If you don't it's a head issue. The head is a pain to get apart and I'd advise RMAing it rather than ripping it apart but this thread will show you how to get it apart.
Aloha Don! I just now tried what you suggested and still nothing so it looks like the head is the problem. I'm not knowledgeable enough to take it apart so I'll take your advise and do the RMA thing. Thanks for your help Don.
When it is brand new and doesn't work - RMA is usually the best option. Problem is, from here I'll spend more than the cost of the light in postage on budget lights so I had to learn.
So if it's going to cost me more than $14.05 or even close to it then it's really doesn't make sense to send it back. I'll find out tomorrow what the return shipping will cost me. If I do decide to ship it back then it will probably take a couple of months before I see it right? Oh well.....
Thanks again Don!
Sometimes DX is very reasonable when it comes to damaged products. I received a $4.28 light that flickered a lot, and I wrote them asking them to send me a new one because both of us would waste time and money on a lengthy and expensive shipping process for something that is worth $4.28. They agreed right away and I tossed out the broken one and I have the free replacement here. Another time I ordered a $10.00 light that was supposed to have three modes. It arrived in perfect working condition, but with one mode. So I told them that it worked perfectly, but it wasn't worth $10.00 without multi-modes. So they agreed to give me a $3.00 credit. So I ordered another one. They sent me the same thing, a beautiful 1-mode light. I sent them a video of the light, that it worked perfectly but was not multi-mode as advertised. I wrote that I would be happy to give it one more try if they make sure that they get it right this time, and that I would pay $2.00 for the replacement. Without complaining or haggling they sent me a PayPal link for $2.00 and my light is now in the "Packaging" stage. So sometimes DX is really very reasonable and helpful with their customers. In other moments they make one want to rip his hair out. But you may want to try sending a video and asking for a free replacement, reminding them that shipping would cost both you and them more money than the cost of the light. Just be friendly and respectful and honest, and use simple sentences, since there is a language barrier. Good luck with that!
P.S. Ah, and another quick tip: If you send a video, you have to package it in a ZIP file, because their upload system only accepts a few file types, none of which are videos.
Thanks sb56637! I just tried doing an RMA but then they require a picture which doesn't make sense because nothing is visible broken but if that is what they require I'll do it. I've never packaged a video in a zip file so my questions are: What software did you use (hopefully free) and is it easy to use? Also, do you have to reduce the file size of the video? If so, I wouldn't know where to begin. Thanks again!
From memory, it has to be less than 2 megabytes in size. I've heard of someone photographing the absence of an order, i.e., their carpet. Their system seems to be rather inflexible but mostly they get it right in the end. They may need reminding though.
Fixing the light is not as bad as it sounds - but you do need a strong tool and a vice (vise) to get the head apart. The glue on the threads is tough stuff. You most likely will also need to find someone who can solder.
I'd wait and see if DX will make it right first. They can be a bit slow but, in my experience, they generally get you sorted out in the end.
Thanks Don! I just took a couple pics and a short video but the video file is pretty big so I thought that I can upload it to Youtube and just email DX the link for them to watch. That should be just as good as sending them the video file right?
Another thing I noticed when my lights came in was that the Akoray K-106 and the TrustFire F20 look exactly the same. I think I'll give one to my friend as a gift when I figure out which one I want to keep. Which one would you guys keep?
If the Akoray is the programmable one keep it.
They're both exactly the same. I can't believe I didn't notice that when I bought them. Oh well....live and learn right?
Can anyone recommend a really good charger for 14500's, CR123's and RCR123's? Also, can you recommend 14500, CR123 and RCR123 rechargeable batteries? Are CR123 and RCR123 batts basically the same? One more thing, will flashlights that take AA also work with 14500's?
Thanks guys!!!
CR123A are 3 volts and RCR's are 3.6V, so a little higher. *Some* lights that use AA's can use 14500's, but not all. There have been reports with some of the AKOray 5-modes of using a 14500 and frying the driver or never being able to use AA's again. But if the light is made for it, many lights are significantly brighter on a 14500.
Best li-ion charger is the Pila charger which is about $45. But you can get a Ultrafire WF-139 pretty cheap at DX, which seems to be what a lot of people have. Not supposed to use it with 10440's though.

For 10440's I use the universal charger which can do just about any battery. Mine only charges to about 4.14V instead of 4.20.

The best lithium-ion batteries by reputation are AW cells, which you can get here:
http://www.cpfmarketplace.com/mp/showthread.php?t=200812
These 14500's are supposed to be pretty good, but most protected cells run a little long (should be 50mm, but might be 52mm) and some are even a little wide:

but I have these which seem to be more like 500 mAh instead of 900 on the label:

Don't know about RCR123A cells since I don't have any. For CR123A primaries I have heard the Made in USA ones are better. I got some from Lighthound.
Glad to hear that your lights came in.....and sorry that you also got a bum one. The last time i did an RMA Dx reimbursed me the postage, all they wanted was a clear pic of the receipt.
I have this charger and are very satisfied with it. Can charge a lot of different batteries.

I can also recommend the 14500 Trustfires Don mensioned.
For any light you have to know if the light will take the lith rechargeables.......on the specs of the light you will see an input voltage from 1.2 - 3.7 volts, if you dont see that then please dont try it...i have burned many lights doing this without thinking. If you dont want to pay the price for AW's then please check out the Solarforce 16340's since there very comparable to AW's. http://www.sbflashlights.com/Batteries-Chargers/Solarforce-16340-p20.html And as you know i also have a couple of these on the way http://www.dealextreme.com/details.dx/sku.26124 in which Don has a couple of them and they seem to be good as well. And if you need some Cr123's by all means let me know...and i will send you a couple bud, i recommend using them only in an emergency situation like during a long power outage where long burn time is needed. I have Energizers, Rayovacs, Duracells, and Streamlight.
Here's a bit more insight into DOA Tank007 E07's, and some of DX's recent replacement deals.

Thanks guys! I just sent DX the RMA along with pictures that really doesn't show anything to help them but I sent it anyway. I also made a video and uploaded it to youtube and sent them the link so they can see that it really doesn't work. So now I guess the waiting game starts.
