I bought these to replace the adhesive foam on my Yakima rack. This foam is noticeably cheaper, it rips easily, and it is really thin. It's in place, but it will have to replaced sooner than later. It's definitely not great for my application.
Pros
Does not compress and is perfect for hoof stand padding.
Cons
The foam may compress and lose its shape over time, reducing its effectiveness in providing insulation or noise reduction
