I guess there's no problem if you stay in all day but what about if you're going out?

Not unless it is winter and you use your husband's/boyfriend's bigger coat. that would be the only way to hide these monstrous things. :)

That's exactly what I did. I used a bigger coat that would cover it up and to start with it worked fine and I had no problem at all. But one day I was waiting in the supermarket checkout queue and putting a basket down I unfortunately knocked the brava just a little but enough to disturb the seal. This caused it to make a huge farting noise and I got some really black looks from those in front of me in the queue. Very embarrassing.

depending on your frame and dome size i believe if you are wearing the small or medium domes you could wear them in public i did with the wide/medium domes but no way with the xlarge/wide domes i have now. Sheesh talk about projectiles.

And as was said if you loose suction and the smart box starts pumping. opps red face. :P
