Bought and put each in once to try, just don't fit or work for me.
I know this is a tad 'yuk' and a bit of a taboo for many, but these aren't cheap and have been thoroughly cleaned then soaked In sterilising solution. I would rather not put them in the bin if I can save someone some money, who might be helped by either or both of them.
Not sure how to do the pm thing but I guess that's the way to go, if you're interested?
