I bought a pack of the 3-ply face masks. Because I was self-isolating, and lockdown has been eased, I didn't have the opportunity to try them until a couple of days ago. From a pack of 10 only 4 have been usable!! The elastic which is meant to go round your ears has broken off from the mask, there are gaps in the fitting and, in my opinion, a substandard product. I contacted customer services who said that because the 30day time limit had expired there was nothing they could do. I explained that I hadn't left the house so couldn't know what sort of quality they were. Customer services were intractable and would not offer a refund although they said they would get someone to contact me........I'm still waiting. Certainly not a product or company I could recommend.
