ONCE FOR ALL Upgrade Safe Mandoline Slicer Plus, 0.1-8mm Adjustable Review (2026)

Adjustable thickness range

The Slicer Plus uses a thickness regulation knob that adjusts from 0.1mm up to 8mm, giving fine control from near-transparent slices to thicker cuts for roasting or frying. A separate shape regulation knob switches between julienne, strip and cube cutting styles, so one unit covers slicing, matchstick cuts and dicing without swapping attachments. That range of adjustment is wide enough to cover most meal prep tasks, from thin cucumber for salads to thicker potato slices for oven fries, without needing a second tool for finer or coarser cuts. For batch cooking, being able to dial in the same thickness each time also makes portions and cook times more consistent across a full tray of vegetables.

Push-down safety design

Unlike a flat mandoline where food is pushed sideways across an exposed blade, this model uses an upright, push-down design where food goes into a vertical chute and is pressed down onto the blade below. That keeps fingers further from the cutting edge throughout the motion, which is a meaningful difference for anyone who finds flat mandolines intimidating. The blades themselves are 420 stainless steel, built into the unit so they do not need replacing, and the body combines BPA-free ABS plastic with stainless steel for the cutting components. That mix of materials keeps the overall weight down while still giving the blade area the rigidity needed for clean, even cuts.

Stability and cleanup

A non-slip silicone base is built into the bottom of the unit to keep it planted on the counter while food is pressed down through the chute, which matters more on an upright design where downward force could otherwise cause tipping. The slicer is dishwasher safe and ships with a cleaning brush for clearing food caught in the blade assembly, a detail that helps with an enclosed cutting mechanism that is harder to wipe clean by hand than an open mandoline blade. Rinsing the chute soon after use also keeps starchy vegetables like potatoes from drying onto the blade before a full wash.

Storage footprint

The upright, chute-based body is bulkier than a flat folding mandoline, so it takes up more vertical space in a cabinet or drawer, and the listing describes a foldable structure meant to reduce that footprint somewhat when not in use. The food chute itself also limits how large a vegetable can go in whole, so bigger items like a whole cabbage or a large sweet potato may need to be cut down before they fit, which is a tradeoff against the added safety of the enclosed design. Anyone tight on drawer space should measure their storage spot before buying.

Who should buy it

This mandoline suits meal preppers who want precise, repeatable thickness control and prefer an enclosed, push-down motion over guiding food across an open blade by hand. The fine 0.1-8mm adjustment and separate julienne, strip and cube settings make it a flexible single tool for slicing, matchstick cuts and dicing. Anyone short on storage space, or who mainly needs to slice larger whole vegetables without cutting them down first, may be better served by a flat, folding mandoline with a wider feed chute instead of this upright design. Beginners nervous around exposed mandoline blades are the group most likely to appreciate the extra separation this design gives between hands and the cutting edge.
