Product review (1 stars): Ruined my bra and barely held the size B
Two things:
#1: I used this one time being very careful to place my bra in correctly, making sure each place latched and closed where it should per the instructions. When I took it out, my BRAND NEW $50 bra was somehow balled up, the elastic sides looked like they had been stretched way beyond capacity, and one of the straps had gotten pulled through the holes. This was all within the INTERNAL enclosure, DESPITE the internal "holding" pieces still remaining in place. I don't know what the heck happened, but I was completely shocked. I'm sending this back pronto and will go ahead and spend the extra money for the official BraBall that I have used in the past with no problems.

#2: The bra I washed was a size B, and it barely fit into the container. I don't know how you'd fit anything larger.

I should add that the bra I washed, while new, is identical to others I have washed previously in the BraBall without any problems. So this is not a fault of bra quality or manufacturing. Skip this purchase and spend the extra money on a BraBall.
