maybe buds could tell you Contact Buds Customer Service at 1-859-368-0371 9am-9pm CST Mon-Fri. or use the Blue Chat now button at the bottom right corner 9am to 9pm Mon - Sat and 9am to 7pm Sunday. and they will help you . We are not buds employees we are volunteers that answer questions.

Hi Kevin and welcome. Buds would likely not know to tell you the truth. it would take checking the Serial Numbers of the current batch that Buds has to check directly with TISAS/SDS Customer Service. You can see if they will get this info at 1-859-368-0371 9am-8pm EST Mon-Fri. or use the Blue Chat now button at the bottom right corner 9am to 8pm Mon - Sat and 9am to 7pm Sunday. Cheers and stay safe!
