I purchased the zyppah device in (b)(6) 2017, and started using regularly in (b)(6) 2017.(see product description below).While sleeping, the strap on my device broke from the posts holding it on one side one night in (b)(6) this year.If pieces had broken off, they could have caused a choking hazard.This potential hazard prompted my reporting the condition to your agency.Incident: no injury.Purchase date: (b)(6) 2017.
