First the people talking about sagging. You need to run this the entire length of the ridge cap or it will look funny. A house down the street has this stuff install and they did not run it the entire length of the ridge and it looks looks terable. I live in Southern California so we do not have ice as other user complained about. I purchased this as I did not want sound to escape. Well very little to escape as possible with still having a small amount of ventilation. I looked at the other options the spinning vents and more. I am glad I went with this vs the other options. It even comes with a roll of long nails for your nail gun I bought three packs and have a roll of nails left over.

The ridge vent was light, easy to install with no waist.

A lot of people stat that this freezes up or ices over? Maybe they are in a more humid environment or have a bathroom vented into their attic. I have never had this problem. Also if it dips down or droops it was obviously installed wrong. I can vouch that if installed correctly it looks great for years. This product has always performed well for me and I have used it on several projects

I have this garbage on my house and it's getting torn off this spring. Not enough air flow. My attic has been insulated and proper soffit vents are the total length of the house with baffles in the attic and I still have ice dam build up. This junk has to go and get replaced by REAL ridge vent.

Rated 1.0 out of 5.0 by MNJoe Not enough ventilation, would NOT recommend!!
This stuff is bad news, very bad news. I would absolutely NOT recommend to install this product.
I had this product installed with my new shingles two years ago. At first, I thought it was great to be done with the rotating Whirly Bird vents, but then I thought that maybe my garage attic was hotter than before. Last winter, the sad realty hit, I realized this product will freeze up and not ventilate. I had major frost build up and when that frost melted, I had dripping onto my ceilings. I now need to repaint half of my mail level ceilings.
Besides the need to repaint my ceilings, of course, I also need to do something for the ridge vent. My choices are to cut in for Whirly Birds, or tear off and replace the Cobra Ridge with something else. Probably going with Whirly Birds....
In summary, buy something else.

Rated 1.0 out of 5.0 by Rose Cheap and still a waste of money
too thin to do anything. this was installed on my house by a professional. The ridge now dips, waves,and looks sloppy. in the best circumstances the product only allows for MAYBE a 3/8 inch ventilation. In my case, because of uneven nailing there are many places where the product is completely compressed allowing for no airflow - which defeated the purpose of the vent system. Given you have to manually install the shingles over the vent material I can't imagine ever getting any significant ventilation or a nice even roof-line using this.

Had to replace old style aluminum ridge due to bad original install(occasional leaks) . The cobra vent is easy to install, just make sure you use longer nails than the ones that come with it if not using a nail gun. Unfortunately, I noticed almost immediately that my 2nd level was hotter in the summer. Then after some very cold winter days, I went into the attic to find condensation everywhere. Never had this problem until I installed this vent. I think it is just too low profile and does not allow enough air flow. As soon as spring is here, I will replace this ridge vent with the "baffle" type that is supposed to be the best ridge vent now (especially for snow regions)

Rated 2.0 out of 5.0 by AchersAway That was a waist of money
I'm not sure if I cut the roofline down to far or not, but this stuff dipped right into the cut. So the rooflin looked like it sagged in the middle. I tore it all out and put the ridgid plastic in.
