It's more of a 3.5 at the moment but previously a 5. The quality of goods is great and it really helps stop my daughter obliterate her skin. My current rating is because though when I first contacted because my sleeves were fraying at the top of the mits, they were replaced, the next time it happened to other ones I was told it must be "because my daughter is particularly rough with them", and referred to the synthetic silk which is more robust. 2 were replaced free but it was actually 4 I had sent photos of. I was told that if the synthetic ones were appropriate, I could purchase more at the site (not in line with their replacement guarantee). When I visited the website the synthetic ones were nowhere to be found. I couldn't be bothered with the rigmorol of contacting again so just ordered more of the usual. It's a shame as I am mostly pleased with them to be fair but my daughter is a toddler - she's not undertaking heavy duty work in them! The guarantee should stand regardless otherwise the durability issue should be addressed and the mits made even more resilient. Being told it was because of my child then only having 2 out of 4 replaced wasn't the best customer service in this instance
