That’s just under $12us. Personally, I don’t care for using AAA in the 3x carrier if I don’t have to. Increases the diameter considerable and since I have a bunch of 18650’s I don’t really have to. Also, if it were me, I think I’d probably be more inclined to opt for something like the Convoy S2+. It will cost you a couple more Euros at the entry level, proven track record, IPX8 (I think), higher lumen output, better modes, smaller diameter, etc…
I also like my BLF A6, which is on sale at BangGood for $20. A lot of options there, too.
