Jim – a mere pin-prick is sufficient to lose a vacuum, but then with a UMAi Bag a perfect vacuum isn’t a that critical and air pockets may occur and are still OK. That’s why I was asking if the bag was puffy or better yet if you could post pictures.
As for posting:
This forum server does not host picture files. Therefore the best way to post pictures onto this forum is to use http://www.photobucket.com and copy the link for the image to the text field of the forum post.
The image link starts with (IMG) http:…..etc
Again – how long has it been bagged? Ron
