Not favorably impressed. Poor instructions on side of box - need magnifying glass to read!
The box included 3 sets of pre-formed plugs. None of these fit well and did almost nothing to cancel noise. In addition, there were 6 pieces of parafin wax that could be molded to fit your ear. These worked best but could come apart in one's ear. Probably be cheaper to just buy some wax and stick it in your ear.
