OG commented about this early on in the development thread: FW3A, a TLF/BLF EDC flashlight - SST-20 available, coupon codes public - #300 by fritz15
You posted a thread two years ago (BLF/Lumintop FW3A Inventor) and said you would never own an HDS because of the price and that the quality was not there. Fun money burning a hole in the pocket now? 
I appreciate the HDS design and the innovation from when they were developed but I can’t see myself ever buying one of these. Price aside, I think that “modern” lights just give us more in so many ways, at a bare fraction of the cost…not to mention cell platform choices like 21700 which up the ante even more. I have always wondered why the infinitely-configurable UI never caught on more than it did, though…we could still totally do that with simple software interfaces and I’ll bet a lot of people would love it. But…ramping is so simple and easy and ultimately gets us to the same places.
