The NESCO VS-12 Deluxe runs a 130-watt double pump with dry, moist and double seal settings alongside normal and gentle vacuum pressure. Serious Eats worked it into its vacuum sealer coverage, where it held a seal through a long sous vide cook and pulled air from delicate items without crushing them. Owners single out the built-in bag cutter, roll storage and viewing lid, and the easy-lock handle that closes one-handed. The recurring complaints are the wait for the heat element between bags and a label on the handle that leaves sticky residue when peeled off.
Full review
Double seal bar and a pulse mode for soft food
The VS-12 pairs a 130-watt double pump with a two-bar heat seal, and Serious Eats found the combination held up under the hardest test a home sealer gets: a long sous vide cook, where a marginal seal fails and floods the bag. It also handled fragile contents, pulling air without crushing what was inside, which is the point of the gentle pressure setting and the pulse control.
Three seal modes cover dry, moist and double, and the pulse function lets you stop the vacuum short for pastries, cut fruit and anything else that collapses under full suction. The bar takes bags up to 11.8 inches wide, so the machine is not limited to the narrow rolls that cheaper sealers force you into.
Bag roll, cutter and window built into the lid
Everything needed to make a bag lives in the machine. A roll compartment sits under the lid behind a clear window, a cutter runs across it, and the easy-lock handle closes with one hand instead of demanding both palms on the lid. Two rolls come in the box, so the sealer is usable the day it arrives.
The unit is bulky for a countertop appliance at 17 by 15 by 9 inches and 10 pounds, and the viewing window is a convenience rather than a feature anyone needs. Build quality is otherwise solid, and owners who have run it for years report the pump and seal bar holding their performance.
It needs a rest between bags
The most common complaint is pacing. The heat element takes a while to come up initially, and the machine wants a short rest between seals, which makes a long batch of freezer prep slower than it should be. Owners also report that seals are less reliable when the double-seal option is skipped, so the safe habit is to use it every time and accept the extra cycle.
The other irritation is trivial to describe and genuinely annoying to live with: the label stuck to the handle leaves a gooey residue behind when it is peeled off. Several owners also found the sealer cheaper from third-party retailers than direct, which soured the experience for anyone who bought at list price.
Strengths
- +130-Watt double vacuum pump ensures maximum air extraction for optimal sealing
- +Includes variable settings with Dry, Moist, and Double seal options plus Normal and Gentle vacuum pressure
- +Built-in bag cutter and roll storage compartment with clear viewing window for convenience
- +Easy-lock handle enables one-handed operation and reduces hand strain
Watch-outs
- −Some users reported issues with the initial heat element warming up and machine rest time between bags
- −One reviewer noted a problematic label on the handle that leaves a gooey residue
How it compares
The NESCO VS-12 Deluxe stands out for its 130-Watt double pump and versatile sealing options, but it falls short compared to the Anova Precision Vacuum Sealer Pro, which offers a more compact design and better double-sealing technology. Unlike the FoodSaver models, it lacks automatic bag detection and sous vide compatibility, making it less convenient for advanced users.
Rating sources
“Her Nesco vacuum sealer is one of her favorite (and most-used) appliances.”
“So, I'll have to spin some off and make two rolls out of it. But for now, what we're going to do is go ahead and use the provided rolls for testing.”
“while I'm still favoring the vacuum chamber machine I'm liking this machine for how easy it is to pick up and take to any room in the house”
