### ⭐⭐⭐⭐⭐ Review
*by R***H on 21 November 2023*

I bought this and knew I would not use it for a month or so because I was on fresh water first to get use to my boat but when I came to it the blue part that goes to the muffs had snapped or was snapped. I kept it in the box and never opened it. But a simple pack of planting glue did the job. Ive used it many times and all works great. I did have pictures of opening the box and showing it snapped but I bought a new iPhone and never backed up my pictures. Worth buying though.
