Great product
Great quality, easy to install and it stays put once you get put it up. We’ve had some pretty strong winds and it hasn’t budged. Definitely worth the money.

Good, but…
Very good water proofing, hard to instal as it’s extremely sticky, and surface not grippy, if wet and steep roof do not walk on blue side. Otherwise will work as intended.

Sticks good
I appreciate the surface texture, makes walking on it much easier. The plastic film backing is split down the middle and peals away nicely. Much easier to apply than grace.
