UL or ETL compliance stickers don’t add to the wow factor of your show. No one in the audience will oooh and aaah over them, and they won’t get an ounce of applause, even if the audience could see them. Compliance stickers aren’t sexy and they aren’t the rock stars of the industry, but they are your best safeguard against poorly-designed gear that could go wrong. And when it goes wrong, you’ll wish you had paid more attention to those little stickers.
