After months of repeated headaches trying to read my laptop screen with a view of my own face reflected in it I thought I'd give this a try. It really works and I soon forgot it was even there! No more paracetamol and signing off early.
If you are looking for those almost weightless mules that have become popular then don't waste cash. These are just as light and just as good -- only of course they aren't pink or yellow or whatever colour you wanted.
