Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
When I opened the package, I thought the item looked very flimsy as it's not as thick as any baker's mat I've used before but, on first use this morning, I was really pleased with its performance. The mat sticks to my faux-granite bench (it's easy to peel off but it's not going to move unless you want it to) and I realised that when making bread I probably won't, in future, need to flour down the mat with semolina unless I want added texture because the dough resists sticking to it, which is very helpful for kneading. It's easy to clean and rolls up quite small for easy storage. I'm really happy with this purchase.
