having been disappointed with 2 previous suppliers who's ferrules wore out within a week I was desperate to find a really heavy duty ferrule that would stand up to the wear whilst walking my dog twice a day. As a result I looked for a health related supplier and opted for the Betterlife Healthcare Heavy Duty Ferrule and I am delighted with the 2 ferrules that I promptly received. I have used the first one daily for over a month now and as I write this it is showing absolutely no sign of wear at all. I have no doubt that when they eventually wear out (could be 2017 at this rate) I will be re-ordering from this supplier. As I said the product was exactly as described - Excellent - Thank you.
