No spill at all or just unworthy to mention?
Apart from a very faint ~1.5m disc @ 5m range..............nothing.
would you be kind enough to show us a long distance beamshot
I am looking for a good thrower
edit:
Don't mind I have found some great videos on youtube on the Ultrafire

How does this one compare same brightness same throw?
Yup, I ordered one too. Probably arrive end of January, knowing DX 
I figured it's cheap, and I don't have one of those "recoil" flashlights; so what the heck...
My son's using the C74 recoil thrower from Focalprice and it's not bad at all. Would be interesting to see how this one stacks up against it
yes, it's exactly the same as the uf-008 in throw and beam shape. Looking at it long enough and there is a slight difference in bin colour.....but hey!...this is DX.
Which design is better for great throw anyway? Long smooth reflector with forward firing emitter or a recoil design such as the above mentioned?
Seems to me that recoils have virtually no spill as opposed to classic throwers. Non recoil could have greater range tho. Any1 knowledgeable on subject can comment on this?
A recoil thrower may give further range but the reflection losses diminish the total light intensity. A forward looking R2 should shoot far enough.
I deleted my own sentence. I would write, you could upgrade the deep reflector shooter with a stronger emitter but you can't change a recoil throwers emitter, or pump more current due to lack of heatsink, but then I realized that a powerful emitter has a wider base and is more of a flooder in fact. These deep reflectors don't work well with even a tidy XM-L.
I noticed almost all throwers are still using q5-R2 emitter class.
XR-E leds have a tighter beam (90 degrees) while XP-G's should have somewhat wider (~135 degrees ?). So they have the advantage to focus the light to a point. These deep reflectors are designed for an emitter with 90 degrees output and they work flawlessly with them. But with a wider angle emitter their walls scatter the light to different angles and can't focus as good.
XP-G and XM-L leds need a totally different, wider head design to throw farther. I guess in the sake of size, portability and modularity (to keep the same parts and machine settings) manufacturers choose to continue their older designs. I don't think there is a real limitation in throw with just the size of the emitter. There must be a way to throw a 1000 lm light while you can easily throw 200lm to 200m's. :)
That is because R2 is the highest bin for XR-E Cree leds (a XP-G would spill to much light to the side)
There were also S1 and S2 cree's with a lumen or two more than R2 but actually never to be found on sale anywhere.
Aren't they successors to XP-G family?
Belongs to species XR-E but im unsure. Time to check...
It is XP-G... blah.
So the R2 are are about the best you can get without going into dedoming emitters.
Humm I am still in doubt between the Ultrafire UF-008 and this Sipik one.
I think the UF looks better but this one is less money ..choices...
These recoil light are not very pracital as EDC but I think a flashaholic like me can't go without
For what reason do people use these? I mean I understand it can work as a spotlight under the rifle or a remote signalling light but I can't find any uses other than a light show toy.
I really don't have a pratical use for a recoil thrower but i would like to have one for no particular reason or greater purpose. Most of us have some flashlights we could live without yet we don't regret having them right?
Yes like those 5 EDC lights I bought last week :) Would make a triple battery SST-90 if I'd carry them altogether. Hımm, is this a sign, is it the time I should get an SST-90?? 
In fact, it is possible to change emitter in a recoil thrower, but it requires a lathe and a lot of work. I have experimented with different emitters in KD Viewfinder (KD version of UF-008), and I found that the best emitter is overdrived XR-C P3 thanks to smaller EZ700 die. Less overall output, but more throw. For the same reason, I changed R2 emitter in my HS-802 and put in Cree XR-C P3 from Romisen RC-G2. Less output, even smaller hotspot and over 30000 lux at 1 m.
Quick question. A typical Q5 "recoil" thrower is going to throw further than a typical FTT (like Romisen RC-C6) zoomed in?
I have not real use of a thrower but I like these "recoils" (by the way, I don't have real use for 40 flashlights either but that didn't stopped me... 
)
it will throw farther than that, but it won't throw farther than an R2 in a P60 host with an aspheric (plano convex) lens. i would have never thought this, but i now know from experience.
and yes, you should have one. if you're up to 40 lights, you might as well have 41...
