Love my jetbeam mini one. My k2 kept accidentally activating. Don’t have experience with the other
where do you see that price?
as far as “copies”
imo Rovyvon was first to commercially promote that thumb size light, but they are not the manufacturer.
other companies have accessed the same factory, and ordered slightly different configurations.
so imo, what makes Rovy more expensive is their profit margin, and feature bundle.
IF you find the Jetbeam feature set suitable, including whether or not it offers High CRI, then there is nothing about the Rovy that makes it a higher “quality” light.
I often see high priced items that are followed by lower price “copies”. imo it is more of a feature set difference, than a quality difference.
buy the one with the features, and price, that interests you. They are all equally likely to be of durable and reliable quality.
ps, I looked up the Jetbeam Mini One SE and info says it has a
CREE XP-G3
I hate that LED and would only buy that light if I was planning to mod, or swap out the LED to High CRI
for me, High CRI is a High Priority… thats my story, and Im sticking to it 
of those, the K2 is the only one with a High CRI primary LED…
I care about easy to implement lock out for a keychain light, and only RovyVon offers that.
RovyVon is more expensive, but because they have the best lock out, that's what I would get.
I really don't understand why other manufacturers don't just copy RovyVon's lock out function.
thanks for the info that you require lockout for your Rovy
it seems the Jetbeam does not need lockout:
I do not own any of those thumb lights, so cant say what the differences are that cause the Rovy and K2 to false activate…
I personally do not own any lights that require lockout. It is one reason I dont own any Anduril lights… I just dont want the extra steps required to lock and unlock, every time I use a light.
With the RovyVon keychain lights, all it takes is a long press to enter (or exit) lock out.
different strokes…
I would not buy the Tiki simply because it requires long hold for off
the Jetbeam and the K2 both have click on, click off, which I prefer… not a fan of long hold…
fwiw, if youre wanting lockout, it is an option, both
the Jetbeam and K2 offer lockout
the Rovy lights have different UI’s depending on which model… I got lost and confused, trying to figure out the differences… that was enough for me to move past the Rovy… I like KISS UIs (not into long hold for on or off)
You can turn the RovyVon keychain lights on and off with a short press.
You don't have to lock them out.
The UI is so simple, it's ingenious, and other manufacturers should copy it.
not all models of Rovyvon have the same UI…
which model Rovy do you like?
does the switch false activate if you dont lockout?
also, some Rovy are bigger than others…
maybe someone can post a side by side lineup
here are two of the lights in the OP:
astrolux K2 and Jetbeam:
pic is a link to the image source from freeme:
here is another lineup I found:
(also links to source)
I have the A3.
I think all of the keychain ones have very similar UI.
I always lockout, so I don't know if it'll accidentally turn on if I don't.
glad you enjoy it
fwiw, this says to turn off requires hold or click to turn off, depending how long the light has been on
“Turn Off:
1) Long-press 0.3s;
2) Working at any mode over 3 minutes, click to turn off”
inconsistent UI for OFF is a non starter for me
Im thoroughly confused by the Rovy models and UIs
Oops!
I was wrong.
I just checked my light.
You have to lock it out to turn it off.
Short presses, when on, just change the mode.
Sorry. 
dont get the astrolux… my broke in half… lol… awful quality on that plastic…
I didn't know that.
I think I'll try to stick to metal flashlights. 
looks like the scales are tipping in favour of the Jetbeam from the comments. it also happens to be the cheapest one.
FYI my sc31 Pro arrived today and its an amazing little light. time to learn all this anduril modes
the price is from aliexpress, not the official store but the most sold listing. add tax/vat onto that price.
Of the 3 you mention, I have only the Astrolux K2, but I like both the seeknite s11, and the olight I1r 2eos better than the astrolux.
nice lineup, so which one of the 2 do you recommend? minus the rovyvon
I dont own any of them… but I would listen to the guy in post #8 because it sounds like the Jetbeam does not require lockout, and it seems to have my preferred UI, which is click on click off, no long hold for on nor off… unless you choose to use lockout
the downside is that the main LED is not High CRI… and has an xp-g3 that I love to hate…
sooo… I cannot narrow the choices down for you
this is why people buy multiple lights to try, and decide for themselves, what they like best
it is also the reason I am glad I have learned to change LEDs for myself… IF I got the Jetbeam, I would plan on an LED swap…
but that is because High CRI is a personal Must Have… others feature set priorities will differ
your homework is to figure out how You would answer your question… for your personal preferences…
please tell me about the s11, seems impressive 300mah battery! is it real?
the only reviews i found on banggood:
Great keychain flashlight. I have Nitecore TIKI, JeatBeam Mini One, RovyVon Aurora A5, and this Seeknite S11 is the brightest of all on turbo mode. It says its 6500 but its about 5500. Very nice tint. Two clicks to turn it ON. Long press while flashlight is off and hold to get into turbo mode. Three clicks to get side white light on then each another click to get white light strobe, UV, red light on, red light strobe, and red/blue strobe. It’s a little bigger than others three but anyway it’s best so far. There is green led under on/off button and it’s on for a few seconds when you turn on the flashing then goes off after a few seconds. When it’s charging this under on/off button led shines red. When it’s full it goes green. It has usb C charging port. And two little magnets on the landyard hole.

A really nice little pocket torch. The main beam is quite cool in tint, but no visible PWM even on the lower settings. The red beacon and the UV light are handy, and the white “reading light” is usefull too. I can do without the “police” red/blue strobe, but I guess it will amuse some folks. The UI is good - simple and easy to remember. The torch is a bit bigger than the JetBeam Mini One SE or the Nitecore Tiki, but not by much, and it houses a bigger capacity battery. USB-C charging port is nice to see too. The charging indicator - red to green is useful, and it appears to show the state of charge of the battery when the torch is first turned on - a nice touch (though this isn’t mentioned in the isnstructions printed on the box) it lights up green for a few secods when the torch is first turned on, and I’m guessing it may light up red when the battery gets low. The torch appears to be decently made, and feels solid. Overall, a very nice little torch, and I got it at a great price on an email only offer. Thanks Banggood!
real enough for me to have 3 of them, it appears to also be sold under the Boruit brand name as well. It has tiny magnets in the base, has higher lumens than the K2 and a usable white light from the side as well as red and blue blinkies and simulated UV…the red, blue, and white mix at leves to appear UV, but is not a true UV led. The same light is being sold under the MIMI S11 branding on ali express for $15.24 US. Who actually makes these little lights? I do not know, but based on what is admittedly little exposure, I do not care either. They are neat little lights, for very little change.
