I don't own their mdc, but from what Malkoff products I do own, my prediction is you WILL NOT be disappointed.
Agreed, the spacing is perfect. My only issue with it was the low-low was so low that in daylight I could shine it directly in my eyes and couldn't tell if it was on. Would end up accidentally leaving it on for hours/days. I would never carry it because i was worried about the battery being drained. Someone else on here recommended the olight 2.4v "14500". It just barely seems to increase the low-low to ~1 lumen, just enough for me to tell that it's on. Now I carry it all the time.You definitely won't be disappointed. I use mine daily, and actually using it right now in bed. I believe the AA MDC has the best mode spacing out of them all. The low low is very useful for late at night when eyes are adapted to the dark.
The original review was excellent when it was written, and is still outstanding today. I've come back and re-read it throughout the years, and just did again today after ordering my first MDC yesterday, a neutral 1xAA. I have lots of Malkoff products but never got around to an MDC, though it's always been at the back of my mind. Outside of a Haiku (which will probably never happen) this will be my most-anticipated light ever, and I thank @nbp and this community for that!
If you choose to buy another one the newer body style is much easier to hold onto. Notice I didn't say "grippy".Thanks for the kind words! I ought to go back a re-read it myself, as it has been so long. haha. Funny enough, I no longer have any MDCs but I still have two Haikus. I wouldn't mind to have an MDC again though. It is hard to get excited about so many of the mass production lights coming out anymore, and returning to some of the classics might be just what I need.
