Held up in serious storm here in AL.
I don't know about all the other reviews however as you can see the tape is holding up in the middle of a pretty nasty storm 25 mph steady wings in extremely heavy rain I did use the squeegee to apply it it is holding past side underlayment to my new new steel roof because I didn't have time to put the ridge vent up
