Does it's job well.
I used this to cap the 2" vent pipe from a tankless waterheater. It's still up there so I think it's good.

Fairly delicate but excellent
If you're used to working with Schedule 40 PVC, this piece is much, much more delicate than typical pieces of that type. It is so by design to maximize the airflow. It certainly withstood the elements including extremely strong winds after installation - so I'm not taking off any stars. Just be aware that you'd want this to be the final piece installed if possible or otherwise be careful not to apply the amount of force to it you'd normally apply making Sch 40 connections.

Heavy wind ?
Seems nicely constructed but I am not sure how it will hold up against heavy wind ?

Simple idea, yet very effective!
I bought this to cover a 2" PVC pipe going up from my utility room to the roof. The main purpose was to prevent rain from falling through the pipe and into the house. After seeing how easy it was to install, I decided to purchase more to cover every vent coming out of my roof in order to prevent debris and other things from going inside. Great idea, very effective, and great product overall.

Works perfectly
These fit just fine. The wind keeps blowing it off because I don't have it glued down so I need to do that.

Keeps the rain out and allows free flowing air
I had a motor destroyed by rain coming down the pipe. This fixed the problem. I suggest using a little amount of pliable glue or maybe bath tub sealer. Just a little to make sure it holds on in the wind, but can be easily removed if need be.
