Yes, I just bought one. Took it out yesterday , day time, viz 2-3m, lots of particulate.
They claim 1700 lumens, not sure I'm buying that. 8 degrees, not sure I'm buying that either.
Strange dimming, the last step goes from 500 lumens down to 80, seems a big drop to me.
Squeaked something wicked when I unscrewed tail cap, a dab of grease fixed that. O ring had stuff on it, fluff, dust, well, stuff. O ring is unusual, it's only a single O ring, but has three ribs.
I didn't buy it for day time usage so perhaps initial impressions are a little premature. I'll take it on a night dive and post back.
At the same time I was using a Tillytec mini uni, it claims 5 degrees, 1000-1400 lumen depending what number you want to believe. It seemed equally bright, if not more than the CX2 which may not be too surprising I guess given its tighter beam but obviously the CX2 was throwing more light.
As at right now if I could only keep one of them I'd keep the TillyTec. Price is about the same.
Not blown away by it.
Bigger in the flesh than I was expecting.
YMMV.
Both use 27100 which is convenient and can use 18650 in both with sleeve.
