In the Grail thread I answered honestly that a Grail lasts up to 15 days and I move on, often it is my latest purchase until something else catches my eye. Fickle should be my middle name but at lease it often has nothing to do with cost......like my present favourite. I keep taking it off and putting something else on.......only to go back in an hour or so.
So if I had to pick my present favourite.. ,......
So what has your interest most at the moment, your favourite albeit maybe temporary 
Cheers
