Yeah… I’d recommend it too. It isn’t perfect but then which <$25 light is?
It says 3.7-4.2V and shows 3x 14500 cells. You’re probably right that it’s like a mini SRK and the body looks like the cells are in parallel, so 3x eneloop probably won’t have enough voltage to make it work.

No, it can take AA's or 14500 batteries, see here same exact light but sold as 3xAA.
You can get a tank007 tk566 with an extension tube for about $20. A decent light for the price. I used to EDC it until I went to my Convoy S6.
Why is this only 2.68€? What is bad in it?
Did you mean the second link to be something else. You linked same one twice.
Third one is too expensive and I would need to pay additional taxes for it.
All these suggestions are tempting me to order at least two different flashlights even tho I don’t really need two…
There’s nothing bad in it. Just an inexpensive zoomie. Decent little light. It will get very warm, relatively quick using it with a 14500 on high though.

FT has a “Fandyfire” version for a bit cheaper:
You just think you don't need two. We can fix that. 
Many Ultrafire or Fandyfire flashlight with XM-L2 LED , cheap and good
Which AA flashlights would that be?
One of my favorite AA torches is the Ultrafire wf606A
I’ll eventually buy the silver version although it’s only a Q2
What is difference between these three?

Solarforce T2 U2 XM-L http://www.solarforceflashlight-sales.com/product_detail.php?t=LF&s=26&id=570
I take Solarforce is most expensive because it has modes. What else makes one of these better than another?
Also how likely are those modes work badly or break down in cheap flashlights like these?
I have one of the FF C3s coming from FT. It’s not arrived yet, so I don’t know if it’s any good, but I mainly am thinking about using it as a host.
The SF T2 looks pretty good (albeit slightly more expensive). Given it’s an SF light, it’s likely better construction quality, but it’s XM-L U2, which is an older emitter, and looks like only takes 2xAA batteries (no Li-ion)?
I think it has a 1.5 - 4.2V driver.
Damn I curse missing this deal 
Click the cn link. You can still get it for $20 plus $3.67 shipping.
Did you mean the SF T2? Their website says:
