I got a reply from sales@ telling that the coupon can't be used with discounted items. However, when I provided the evidence that cart did show the wrong price, they gave me two alternatives: cancel the order or accept a free battery for compensation. I turned down the battery offer, but gave a counter offer of Olight S10/20 diffuser => They agreed to add that to my order, free of charge. Obviously a monetary compensation would be very difficult for them and, on the other hand, sending out goods is easier.
After all, they provided quick & good customer service (I was actually amazed!), so: I'm a happy camper, again. :)
Damn, I was really hoping the larger switch was a "master" clicky switch, and the smaller switch was momentary for changing modes. Unscrewing the body slightly on the SRK to prevent battery drain is kind of hokey to me.
Oh, so the big button is a "Power" button - hold a sec to turn on & off. Tap to change between "first mode" (your memorized ramping level) & then high. That it? Another tap to go from high to the "first mode"?
