Things I liked:Convenient to use, quick to insert into your ears. Things I would have changed:The plugs are nice and soft but the the plastic hoop that holds them is far too stiff and prevents the plugs from aligning properly in my ears and affects the comfort. They may fit others better. What others should know:I bought for general shop use and shooting AGs, they offer enough protection for PCPs and machine tools. Do not use for firearms, they will not offer adequate protection.
