Try both Email and BLF PM. It took 3 months for him to respond to my multiple emails for my Enogear AA a few years ago. He threw in a freebie that time too.
Just wait a while. Jack is real busy and doesn’t check messages and emails for days or even weeks at a time. I’m guessing he is focused on the new lights right now. But he will surely get back to you.
Jack had over a dozen “defective” lights shipped to me to check. More than half of the lights were fine and I couldn’t reproduce the claimed issues. I suggested to him from then on that he should request customers to show videos of the defect before allowing a return. I’m glad he listened. Business is hard for small businesses when people treat returns like it’s Costco.
