They work 100%. I haven't tried minis - as I don't really see the point, but medium and super - fit the bill!
The price is obviously more than other brands due to packaging - which doesn't make me want to buy them anymore than a plain packaged item. But, hey, a tampon is a tampon! They work and thats what counts :)
Even though that time of the month is awful the bright coloured packaging sort of lifts your day! Great product, will be sticking with this brand
