Hi from Slovenia
Sadly as I don't speak German I've only lurking so far...(could somehow still understand basic meaning of written words and with little help from crude machine translation)
So I hope you don't mind to much if I write in English (although it is also not my prime language and my English verbal skill are also limited)
Based on recommendations in this forum I've also bought B20red - packet arrived yesterday so I check it only briefly at my backyard...
I feel that I owe you some findings about, so here we go:
1.) Support and conversations with Qualityflashlits/Susanna is not less than great!
Admittedly going through usual nightmare advising ME as customer/buyer is really not an easy task.
She went through mentioned nightmare flawlessly and she certainly have more trust to strangers than I...
(I still need to additionally pay for some other light she voluntarily put in packet, - according to prior agreement, that I will pay for it later, AFTER I receive it).
Thank you. Highly recommended web store indeed.
About light:
1.) After numerous mind changing red/black/red...I've finally settled on girlishly and discounted red...well color turn out not be bad at all...
Heh, it even matched fine with chrome red button on lefty xlr button and red seat post clamp...

)) besides I bought light for ride not for showcase - at night everything is dark anyway...
2.) Light and accessories didn't came with that nifty storage bag as seen on photos or reviews...... ;-(..smrc...It is just cardboard box with foam, although clever designed...
(oh well... I've guess it is about production cost cut...I'll don't miss bag when riding...maybe would benefit while on storage to keep things arranged)
3) Quality seems very OK, and light indeed feels like some jewelery....!
4) I didn't perform as much testing/riding (maybe tonight). It is my first light as such caliber - previously I had something like candle (even light from my rough Samsung phone was better!) so I'm not so qualified to give some light beam review..as difference is indeed huge. It would be beneficial if light beam could be wider, but my MTB riding skills won't catch up need for something brighter and wider. Maybe just one subjective thought - probably most usable setting is "medium" - but then only one LED is on.....so because of that beam feels somehow narrower than two LED is on...Maybe latter I could compare light with friend's MJ 856.
5.) Having separate switch is real benefit - one could easily get used to and would miss flashlight without such feature...
6.) "Stupid" strobe mode seems not stupid at all - It is designed not to easily/accidentally turn on. And it is not that real disturbing strobe as seen on tactical lights - it is merely alternately blinking between both LEDS.
7.) A usual my bad luck! I've got somehow defective (Y switch, production version) cable. It is just small glitch - screw cap which secure plugs between battery is assembled reversely - preventing plugs to be securely tight fitted together. But Susanna is already aware about and dealing with.
Until replaced, some scotch tape will do the trick I guess...
8 I've mounted light via supplied handlebar mount and don't know jet if helmet mounting would be better. I found really nice and affordable helmet mount which seem it could fit as it is actually designed for B20....
Adapter rails are suspiciously similar to Cateye adapter..."Cat Eye Helmhalterung"

Probably in fact just blatant copy but I wouldn't mind as long as it fit. But I wasn't able to measure dimensions of adapter...Could some of you check/proof actual fitting before I take plunge and order to Slovenia?
Best regards
