I was very happy with the functionality of this item. The level of noise reduction was great! However, for longevity, i am displeased. I only used the them 3 times before the left side ear protector broke a hinge post. This effectively ruined the hearing protection of the unit because the one side will not stay attached. This unit still has a functioning face shield, so it is not entirely useless, but if i had known that the hearing protection wouldnt last i could have just gotten a face shield for significantly cheaper.
