    • Easy to use.
Strong snaps, stay attached even under heavy pressure, but they pop off easy also when one wants them to.

    • Great Product
Work great! Didn't have to put more snaps on my boat - just used the extenders to snap open the isinglass.

    • Good and Durable
Very well made. I use it to add adjustment to my mooring covers.

    • Great!
I bought a new boat and past experience taught me the frustrations of snapping a tight-fitted cover. I ordered these before I even launched the boat! They are excellent and removes the frustration of snapping on a cover!

    • Perfect fit
My boat cover has been difficult to stretch to reach each snap. These boat cover snaps added plenty of leeway and has made covering the boat so much easier. I highly recommend these.

    • Snaps Broken on Most all of the Straps
Review Image by Sue Sue
The snaps were great but one by one they came apart. We only have two good straps left. All the snaps do not stay on. Seems that they were not clamped tight enough. Pretty expensive product if they all break. We are back the drawing board. Afraid to buy more because not sure if they will be the same. ... show more
