Mine took 4 days to my door. I got in on the first order go round and was the first to receive one.
The second one I ordered oct.12 and should be here tomorrow oct.18. 6 days but I placed the order late friday.
The 3rd one I ordered oct.14 on sunday and looks like it will be here tomorrow also oct.18, 4 days again.

I studied this driver all night last night. Searched every where for some post explaining this driver or some kind of info. Its pretty scattered info.
This driver uses a SD3033 (PAM2803) for the boost IC.
Datasheet SD3033 http://aitendo3.sakura.ne.jp/aitendo_data/product_img/ic/led_driver/SD3303/SD3303.pdf
PAM2803 http://www.s-manuals.com/pdf/datasheet/p/a/pam2803_r2-2_diodes.pdf
Same IC as far as I can tell and The header of my pdf for the SD3033 says “PAM2803”
wight done a lot of work with the PAM2803 in this thread. [WIP] 15mm PAM2803 w/ ATtiny13A rough layout / possibility
I read the entire thread last night still didn’t come up with what I need to know about this V11R driver using a li-ion cell.
I purchased a few better higher value parts from Arrow electronics today to try and mod this thing with what I think might work.
One of the main parts had to be shipped from HK so it maybe a week or 2 before I get to try this.
If anyone has any info to add about this driver, I’d gladly take suggestions from someone who knows this stuff better than me. I’m just self taught threw lots of reading and blowing up stuff.

Some of the most interest things I found about this IC was in the Application Information in the datasheet about half way down the pdf.
