I really like the clciky cap with the cran port! I may be amongst the minority when I say I have never really liked thesurefire plugs not the port/clicky capspf surefire, mostly price wise. This cap as a very tactile button, crane port is nice and tight but not too tight to where your plug gets stuck inside. The ring on the crane port moves! You can spin the port to where it'll fit the best on how you mounted your light, I did not know this cap did this and it is an awesome innovative feature!
My only gripe about the cap, is the bulk.it is definitely alittle bulkier and heavier than I expected, and I know there is only so much they'd be able to change dimensionally, but I think if they went to the least about of material possible while retaining the current feature set this would be handsdown the best cap on the market
