We bought a Vacmaster Pro 110 off of Amazon a few months back. It has been working fine, however today we are trying to vacuum seal some bacon and it won't work right. It is staying on the vacuum part of the operation for a very long time, then when it finally switches to "seal" it loses some of the vacuum. Anyone else have this problem? If so, how did you resolve it? I tried calling ARY, however they are closed on the weekend apparently.
