I liked the idea of this product, but as soon as I opened the container it comes in, I couldn't breath. The off-gassing of the product was so severe, it triggered an asthma attack. I took it out on my porch to unroll it to leave it open, hoping it would finish and be useable, only to discover it was already torn when I unrolled it. I left it unrolled outside for 24 hours, but it still was unbearable when I brought it to my sewing table. I also realized that my bobbin area wouldn't be accessible with the product installed, so the benefit of the slick surface would be overly-offset by cons of the super-stink and lack of accessibility to the sewing machine. The fragility is also a deal-breaker for me. It was a waste of money for me.
