Let me put it this way
imnsho, the RRT-01 does several things better than an HDS Rotary
but, there is no fan club for the Jetbeam, so nobody but you, I and a select few in the know, use the RRT-01 as our EDC…
the RRT-01 is simpler, smoother ramping, lower low, higher high, and less cash
but like I said, there is no fan club, and if I said all this in front of the wrong people, they would think there must be something wrong with me, and would never listen to anything I say ever again
but I did my job already, HDS now offers a ton of High CRI LEDs, all because of me… I need to convince Jetbeam next, but until then CRX is on the Job!
