Strengths: If you're a big girl, nothing is going anywhere in this.
Weaknesses: You do have to be big for it to do the trick - I bought one when my chest increased from a B to a C/D cup during pregnancy, but there was still room to spare in it. It is a deeply, profoundly unattractive garment. I have never worn anything that made me feel quite so unsexy.
Overall: Very good if you need SERIOUS upholstery. Otherwise, go for a Shock Absorber.
Strengths: Good value, very supportive, great cushioning for road running but enough grip for even trails. I have also raced in them and they've done me proud.
Weaknesses: I get through a pair every 6 months and I only do 5 to 10k a week. High mileage runners would probably want something longer lasting
Overall: I love these shoes and wouldn't run in anything else - the excellent cushioning gives me the confidence to dig in and up the pace, even on nasty hard pavements.
Strengths: Comfy, good support, straps don't slip off, and the fastenings are at the sides so if you wear it down the gym aswell it won't dig in your back whilst you're doing sit-ups!
Weaknesses: None really - cup seams can chafe a bit if you get really sweaty, but I think this is the same for every bra.
Overall: excellent for the smaller chested lady (like me - B cup)
