Hi Dec, last year i bought two, one for myself and one for my daughter who was having a really rough time in her first year of having periods.

I thought it was ok, i couldn't say it made much difference, my daughter likes hers ( it is pink)

The main problem i had was; it often would fall into the loo when i went for a wee! (The two pieces are magnetic and attach onto your knickers) In the end i was worried i would be at work and one piece might fall down my down my trouser leg and pop out!
