Wow! You might want to hire a PR professional because your company is coming off like a bunch of jerks. Also, a regulator falling off and getting lost during testing doesn’t say a lot about your quality control, which is unfortunate since this will test your customer service skills going forward and I’m worried you lack in that department as well. Best of luck with your business.This is NEX Underwater Products, we test regulators on a regular basis in this area. Currently you have a regulator that does NOT belong to you. This is a regulator that is a part of testing. Please return ASAP as this is property of NEX. Scuba Board has also been notified of this.
