If BIEL had exhibited at CES I guarantee there would have been at least 3 investors complaining that BIEL spends too much money attending trade shows.
I have attended several CES events TBS, as the location, Las Vegas, might indicate it is all about sexy, flashy promotion. The link below to a CES article is a prime example with its feature photo of a robotic dancing stripper.
BIEL is not sexy or flashy but it is an effective drug free pain reliever and when you are hurting that can be priceless.
