I bought the imitation Brava pump 
To be fair to the seller, it's not really an imitation of Brava and it can actually do a bit more than the brava pump can. On the other hand, it's much bigger and louder than a Brava box, so I won't be tucking it into my bra any time soon. It's a homemade pump that can maintain low or high pressure in a set range. He says it can maintain pressure as low or lower than -1.5hg (like the brava) but he's worried that the motor will wear out much quicker that way, because it will constantly be kicking on and off as it tries to maintain a vacuum at such a low pressure. He doesn't seem to think that brava domes will really do much to prevent this, but it seems obvious to me that Brava uses sticky silicone rings and body adhesive because they think it will help maintain the vacuum pressure and keep the pump motor from having to run constantly. I guess I'll have to find out the hard way.
