Adhesives such as PP products are hard to work Cracks where R and so on are wrapped in thin aluminum tape and integrated with plastic rods? You can repair that goes beyond emergency by rubbing until you do. This price! But it is thicker than 100 things, there seems to be considerable use of heat resistant products and double use of both sides in proper use etc.
I bought it because it was attracted by the cheapness, but in this case it was better to buy it at the home center. A quality that does not differ much from 100. We do not know because we do not compare the amount, but depending on the situation, we may choose private brands with lower prices. I also want pictures and comments that let you know the quality as you can not look at the actual thing and buy it.
