It would flash "Low Battery" even when I installed fresh ones. I haven't had a chance to use it much but I've bought it over a year ago so the warranty has expired. If it doesn't flash "Low Battery" then I would be able to use it 3-4 times and start flashing "Low Battery" again.
Where can I send it to have it repair? I've used it less than 100 flashes.
Added (1). I'm using the AA battery from Costco. The brand is Kirkland. Would this cause it malfunction?
