Strengths: The right 'power' flattens boobies so there is no painful bouncing going on
Weaknesses: Despite them being one of the most accessible brands (in lots of shops and on lots of websites) I find it difficult to get level 4 support - and level 3 doesn't quite cut it!
Overall: My bra of choice, but only because these things are so expensive I am not keen to shop around for a potentially inferior product! And always go for level 4!
