Are you kidding?
You sold a beta-test or engineering sample in the guise of a finished product!
I also emailed my order #.
I wish they would send engeneering samples for review before they start selling em
The 2 main issues, bad UI, breathing mode without proper LVP and the missing AMC7135 for low modes are the things I clearly found in my review could have been fixed
fixing problems after release makes a lot trouble and extra work
I agree with ToyKeeper above, (though I sympathize with everyone who has already swapped emails with CS).
Here is what I sent:
If we all keep it simple and concise, things will go easier for everyone.
I got a reply this morning stating that they would be shipping me the fixed body tube and USB cover.
I agree with FindThisHumerus, well, at least with his name 
I have a lot more puns where that came from!
^ this.
Many here would have been happy to test samples and be helpful in making this a great light.
I didn’t know about a missing 7135.
Do you mean there can be a 7135 soldered on the driver board, or did they not incorporate a 7135 in the PCB design?
Aha… 
I bet the MCU doesn’t even drive that channel, so that retrofitting them would not work either?
What size is the driver?
I do not know yet.
I’ll try to solder them.
21 mm
Thanks!
I wouldn't waste your time. There's no way the presence of those chips would be auto-detected and used if present. Might be possible I suppose, but I'd be in the range of 98% it won't make a difference. You are giving a lot of credit to the writers/designers of the firmware, which, sorry to say, probably don't deserve a lot of credit for how the firmware works.
Interesting the pads are there though, if they truly are wired up to a MCU I/O pin, and the output wired in to the output of the FET. Also of interest would be to determine what MCU they are using..
Honestly for me, it's pretty much a waste of time - I'd rather do a driver replacement and get what I want.
Sometimes the “cheap stuff” game we play here reminds me of a quote from WarGames:
“A strange game. The only winning move is not to play.”
They all must not be aware of the problems, but their shop/support-system could be aware of it. It could be possible that there are informations for each supporter for each individual product. If there are layout-problems, every supporter can read it.
But it seems that they dont have such a edv-system.
Anyone want to make a guess about how long the replacement tubes and USB cover might take?
I was asked in an email if I wanted the replacement tube held and sent with the USB cover so it leads me to believe that the tubes will take less time to create.
Did anyone get a similar question in their email responses?
Yes, I got the same email.
Hello.
I ordered my S42 on pre sale May 09 and it arrived today.
Meanwhile, I have also ordered Aspire 18350 batteries that arrived a few days ago.
As everyone knows now, the battery tube is too short, but I managed to put an Aspire 18350 battery in the light.
This obviously resulted in the positive end being pushed in a bit and the same occurred to the bottom of the battery.
(You have to sacrifice a bit to see the light …)
Beyond this, the light works as advertised, but it gets fast hot in turbo.
I switched to mode 2 and the light had been on the table for a half hour. When I tried to turn on the light, it would not work through the four announced modes. It just flashed in a very low mode every time I pressed the switch. I had to loosen the end plug and put it back in place again.
Then the light came on in mode 1 and worked. Then switched to mode 2 that also worked ok.
Also the “dragon breath” and the lock out works fine.
However, i have reported back to BG that the length of the battery tube is too short so I hope they will send me an upgraded tube when this is done. (I do not want to destroy any more 18350´s.)
Likewise, the USB charge port cover is a joke. Hope they can come up with something better.
In addition, I have the 18650 tube in order - so we will se if that is long enough.
Thats all…
My 18650 BLFa6 astrolux s41 tube does not work on the S42
