Yes, also the blinky modes are memorized. You are fine as long as you use it more than 1s at a time.
Seller (or manufacturer) flashes the drivers.
See your PM. :)
Half time results:
Judging by the answers so far, it seems like the three settings which can be modified with stars would be:
1. Mode order
2. Mode memory
3. Turbo timer
..which would leave the lowlow mode enabled and hidden modes available. At least I would be ok with those settings. Any objections?
I have to add that turbo timer is a requirement by the manufacturer. They say that 6x7135 is the maximum they are willing to do, or warranty will be void. 8x7135 + turbo timer should be ok for them. That would leave the buyer the option to disable the turbo timer and thus void the warranty. ;)
