Got a Zip EZ last week. Super sale price. Used it one day. Left it in the watch pocket of my jeans and yep, it went through the washer. Caught it just before it went into the dryer. I figured that wuzz that. I opened it up and it didn't look too wet so I changed the carto and tried it. It works fine. Took a few good draws but decided to leave it alone for a few days. I don't think that would work with very many pvs.
