Bonsenkitchen VS2100 2025 Vacuum Sealer Review
Overall Verdict
The 2025 BonsenKitchen is a meaningful redesign of the original VS2100. We don’t have any food mode in the traditional sense, just functions – Seal, Vac & Seal, Pulse Vac, and Accessory. And where the VS2100 could seal a bag in 6 seconds with weak suction, this version pulls 51 kPA consistently, which is a measurable step forward.
The result is a sealer that's closer to average than its predecessor was to the bottom. It's quiet, safe, and inexpensive. But the sous vide test required three attempts, and the crunchy food breakage of 31% is higher than several cheaper sealers managed. For basic food storage, it's solid value. For more demanding applications, check the best vacuum sealers in higher categories.
Things We Like
- Notably quieter than most sealers -- matches the original VS2100's low noise level
- Consistent suction across both test sessions at 51 kPA
- 3-year warranty -- generous for this price
- Very affordable
Things We Don’t Like
- Sous vide test required three attempts
- 31% crunchy food breakage -- worse than most budget sealers in this group
- Lid is stiff and difficult to close consistently
- No bag hooks, no drip tray
- No specialized food modes for dry or moist foods
The 2025 BonsenKitchen replaces the original VS2100 that launched the brand as a budget staple. We tested a new unit for a week in the lab to see how much the redesign changed things.
6.0 Performance
The 2025 BonsenKitchen scores 6.0 in performance -- slightly lower than the original VS-2100’s 6.2 under the old methodology, though the comparison isn't direct. Suction has improved substantially from the original’s 34 kPA to 51 kPA of this version. That’s real progress in suction power. Dry food handling is where the problems sit: crunchy breakage is higher than most budget sealers in this group, and the sous vide seal failed twice before holding on the third attempt.
6.2 Max Suction Strength Test
The 2025 BonsenKitchen reached 51 kPA in 27 seconds -- identical across both test sessions. The 51 kPA figure clears the 45 kPA minimum threshold we look for, which means this sealer can properly evacuate a bag of dense dry food -- something the original VS2100 (35 kPA) couldn't reliably do. The cycle time of 27 seconds is on the longer side. Compared to the BonsenKitchen VS2100's 6-second blitz at 35 kPA, the 2025 version trades speed for actual sealing power.
6.9 Crunchy Food Breakage Test
The 2025 BonsenKitchen broke 1.41 oz of the 4.5 oz input -- 31% breakage. That's a worse result than the original VS2100 (3%), though the original's low breakage was largely a consequence of its weak suction. More suction means more force on fragile items. Compared to the MegaWise VS6621 2025 (22% breakage at 44 kPA), the 2025 BonsenKitchen's higher breakage reflects its stronger motor. The Pulse Vacuum mode is the intended solution for fragile foods, letting you manually control suction duration.
5.0 Beef for Sous Vide Test
The 2025 BonsenKitchen needed three attempts to achieve a clean sous vide seal, matching the Nesco VS-12 and the POTANE VS2690 for the weakest result in our current test group. The first two seals failed to hold under water bath conditions. The third attempt held.
This is the same failure pattern seen in other single-mode, higher-suction sealers. The motor pulls hard enough to draw moisture toward the sealing bar during moist food cycles, compromising the seal before it fully sets. The Moist mode helps by slowing the cycle, but not enough to eliminate the issue reliably.
6.3 Design
The 2025 BonsenKitchen is a better-looking and better-built sealer than its predecessor. The control panel improvement is a clear upgrade – you have five tactile buttons that are logically arranged. The lid is the persistent weakness.
In the Box
- 5 pre-cut vacuum bags (8" × 12")
- Air suction hose
- External interface × 2
- Instruction manual and tutorials
Dimensions
The 2025 BonsenKitchen is roughly the same footprint as the original VS2100. At 2.7 lbs it's slightly heavier, reflecting the hinged lid and internal bag storage. It won't crowd a counter and stores easily in a cabinet.
7.5 Build Quality
The switch from a detachable top to a conventional hinged lid changes the feel of the sealer. The original VS2100's removable design was practical for cleaning but inherently flex-prone. The 2025 version's hinged lid is more rigid and feels more solid when you handle the unit.
The outer housing is plastic throughout, with a silver finish. Panels fit together tightly with no gaps or rattles. The foam gasket and heating bar inside the channel show no manufacturing defects. The 3-year warranty -- longer than the 1-year coverage most sealers in this price range offer -- suggests a degree of confidence in the build's longevity.
The one trade-off from abandoning the detachable design is that cleaning the vacuum channel is now more involved. You can't lift the top half away to access the base directly.
8.0 Control Panel
There are five physical buttons in total -- Seal, Vac & Seal, Pulse Vac, Accessory, and the Power button. The Pulse Vac button is the notable addition over the original: hold it down to vacuum, release to stop, then press Seal to finish. This gives you manual control over suction duration without needing a separate Gentle mode.
The buttons are clearly labeled and the indicator lights above them are easy to read. Layout is clean and requires no learning curve.
5.0 Lid
The lid uses latch locks on both sides. The mechanism is where the 2025 BonsenKitchen loses the most points in design. The locks require firm, even pressure across the full width of the lid to engage simultaneously, and the force required is higher than most sealers in this group. One-handed operation is not realistic. Both reviewers found the lid the most effortful part of using the sealer, and the experience didn't improve meaningfully with familiarity.
The hinges are solid -- the lid doesn't wobble or creak -- and the underlying structure is sound. The problem is specifically in the latch mechanism.
0.0 Extra Features
No extras in our scoring criteria. The sealer has no bag holder, bag cutter, bag hooks, or drip tray.
7.8 Usability
The usability score reflects the same strengths the original VS2100 had -- quiet motor, clear indicator lights -- carried forward into a sealer that's otherwise more capable. The lid is the one consistent friction point.
7.5 Ease of Use
The four-button panel is easy to learn and straightforward. Pulse Vacuum adds a useful layer of control without complicating the interface. Day-to-day sealing is smooth once you've established the two-handed lid routine.
Without bag hooks, bag alignment takes a little extra care. The vacuum channel is wide enough that it's workable, but hooks would help.
10 Safety & Noise
At 76.3 dBA, the 2025 BonsenKitchen is one of the quietest sealers in our database -- matching the original VS2100's 76.1 dBA almost exactly and significantly quieter than most of the field. Safety markings inside the sealer are clear and well-placed. A perfect score.
7.0 Indicator Lights and Chime
Five indicator lights -- one per button -- illuminate to show the active mode. Bright and readable. No progress bar and no chime, so tracking cycle completion means watching the panel. The indicator system is functional but not comprehensive.
