Seems very similar to the Fenix E03R in shape and UI, though a little brighter and a little larger battery (and the choice of UV for the secondary light too, of course). Based on the numbers this reports though, the beam is a bit more focused. The Fenix is so floody that I tend to use the high mode just to get any intensity. If the price is right, this might replace the Fenix on my car keys.
Looks like the TrustFire Minix is $18 on eBay.com and $18.25 on AliExpress.
I'll wait until I get a coupon for one of those sites. 
i’m supposed to be getting one any day, i won it also
will review

hm i thought it would have both red and UV, now i do not know which one they are sending

Have a look at the first picture, top right keychain light:
That seems to be a Minix. Not sure if this image was later inserted. Posted 07/21/2021, edited 08/11/2021.
Thanks for your review and impressions Unheard 
I guess I will receive mine in the next days too, let’s see what I’ll get 
Hope you both will be happy!
Feel free to add you reviews here if you wish, but anyway, I’d love to read them.
I like the shape of this keychain light. It’s more sensible than a tube, which is why Nitecore went with this earlier on with their TIP. But Nitecore botched the UI. What a fiasco. It sounds like this UI solved the problem more sensibly. Press+hold 0.5 sec to turn on. Double-click for electronic lockout. Why couldn’t Nitecore do this? Unreal. I bought several TIP lights for family members. What a disaster. Battery problems. High parasitic drain. None of them are being used now. I don’t trust Nitecore for this type of flashlight any longer.
I would buy one of each if it had a clip
Yeah I’ve been skeptical of anything from Nitecore. I have a specific interest in one light (NU05) because of its unique form factor, but I’m not expecting much from it.
The rectangular light that made the most sense to me was the Surefire Sidekick, but Unheard mentions that it has had reliability problems, which seems unfortunate and un-Surefire-like. I hope they can get them sorted. I wonder whether the Sidekick is a “real Surefire” or is something they bought on Alibaba. They dropped the price drastically since introducing it. Before that, though, I’m sure they could have fixed any issues it had.
My runtime is way off their rating. I got 35min on High and 58 min on Med. Specs show 56min High, 136min Med. Still need to measure Low. I always state the ANSI spec though
Can you post your diagram here?
Room Temp - 20°C without cooling. To get their specified runtime it would of needed to be hotter than the ANSI testing allows of 22 ± 3 °C or perhaps my battery is a dud
It’s complicated open the case? Don’t see any screws
for Led access and swap it.
Fairly certain it’s glued. I would have loved a 4000-5000k white led
it’s all glued or at least wedged together[interference fit]
I’ll have my video review sorted soon. It has very impressive range, I just feel like the low mode is too bright
The runtime is far below the specs. I got 150 min on Low instead of the 327
I supposed removing the rear cap was enought for pull out all
that is probably how they put it in, from rear cap - but if there is glue it will not come out whole

Thanks, good analysis of the problem. Steps down too late. The energy management is apparently not perfectly working to meet the stated specs.
