i've heard a lot of people give it good reviews..although i think most people use it under fleece. I would, anyway. I don't know about using it..maybe someone who uses it can tell us what they think.. I think [MENTION=26641]G_Piggler[/MENTION] uses it
I sure do and I like it! On my largest 3x2 area, I clip one layer of ZORBII (that's II, it's already sandwiched between a soft wicking fabric) under one layer of fleece. Honestly, in 6 months my girls have left only about 5 spots down on this level since they mainly wee up in their kitchen. On the second loft/upper deck floor, I started using ONLY the ZorbII and aside from seeing the spots on the boring light solid color, it works just fine. My piggies have beds on this floor, so it doesn't seem to matter that it's missing the nice cushioning additional fleece layer.
I sewed a close stitch perimeter around my ZorbII pieces, wash in warm not hot, dry on low, and mine shrank in length just a bit and does not mis-shape during subsequent laundering.
I also sandwiched ZorbII in their fleece beds and hammocks. Quick wicking and drying is the name of the game, and this stuff works for us. I ordered mine from a site starting with Waz-something if memory serves.
