Got this to insulate the exterior walls in the attic I was finishing. Worked as expected and had no issues with packaging or shipping. I find the pink stuff to be softer to the touch than some brands, but cutting it is slightly more difficult than some since the kraft facing on the pink stuff isn't very stiff, but it's not really an issue.

Expensive but worth it.
I use this type of insulation in all of my projects now - walls and ceilings. The finer-grained fibers are easier to cut and work with and they don't create as much dust as the traditional types of fiberglass. The higher R-value will keep you warmer and save you the extra cost in the long run. The vapor barrier is a good, heavy impregnated kraft paper. Great stuff!
Although this product is advertised for use in 2x6 walls, my project in the photo was re-insulating an old extension that had a 2x6 ceiling joists and limited space for layering extra insulation. I used two layers, one above the joists (I ripped the vapor barrier off so it could breathe) and the second layer with the vapor barrier stapled to the joists. The extra R-value was very good to have in my limited space, and gave a good, tight final installation. The kraft paper was strong enough that no extra support was needed.
