SupMaKin Upgrade Safe Mandoline Slicer Plus (Blue) — Adjustable Vegetable Slicer & Chopper

If meal prep is where you lose time, the SupMaKin Upgrade Safe Mandoline Slicer Plus is built to speed things up without turning slicing into a risky chore. It’s a mandoline-style vegetable slicer plus a chopper/dicer setup for vegetables (and some fruit), with an adjustable thickness range and a feeding port designed to keep your hands farther away from the blade.

That said, it’s not magic. Mandoline slicers can be a little unforgiving at first, and you’ll want to follow the manual before you expect consistent results.

What it is and what it’s for

This is a kitchen mandoline slicer that’s meant for “faster, safer prep” tasks like slicing, stripping, dicing, and julienne-style cuts. The idea is you can do a lot of prep work in seconds for things like salads, sides, and batch cooking—especially if you routinely cut onions, cucumbers, tomatoes, potatoes, and similar produce.

On paper, the product leans into two themes: a safer feeding setup and an “easy repeatability” approach where you don’t need to keep changing blades for different cut styles.

Where it stands out (and what you’ll notice day to day)

The most noticeable day-to-day benefit is the adjustable thickness. The slicer is described as adjustable from 1–8mm, which is useful when you’re trying to match textures—thinner for quick-cooking veggies, thicker for more bite.

It also targets convenience. The feeding port is listed as 3.9 × 4.7 inch, and there’s a container chopper so you can process more food at once. There’s even an upgraded handle that automatically rebounds after pressing, which should reduce effort during repetitive prep.

Material-wise, the blade is described as rust-resistant 420 stainless steel, paired with an eco-friendly ABS shell and a non-slip silicone base. For a kitchen tool you’ll use often, those details matter more than they sound.

Ease of use and cleaning (the part people forget)

The product is positioned as easy to use, with a handle that rebounds automatically after pressing. That’s the kind of small design tweak that can make repeated chopping feel less like a workout.

For cleanup, the promise is simple: one-click disassembly and dishwasher-safe components, plus a cleaning brush. If you’ve ever owned a slicer that turns into a “cleaning nightmare,” this is the feature set you’d hope for.

One limitation to keep in mind: the listing explicitly asks you to read the manual carefully before use. That’s a good sign the tool has a learning curve—so if you want instant results with zero setup, you may need a little patience.

Who it suits (and who should reconsider)

It’s a solid pick if you do meal prep regularly and you want one gadget to handle multiple cutting styles—especially if you’re slicing and dicing the usual lineup (potatoes, cucumbers, onions, tomatoes, and more).

It may not suit you as well if you’re expecting a “set it and forget it” experience. Like most mandoline-style slicers, consistent output depends on technique and using the feeding setup the way it’s intended. Also, if you only need occasional chopping, storage footprint and setup time might feel like overkill.

Buying verdict

This SupMaKin Upgrade Safe Mandoline Slicer Plus is worth considering if you want adjustable thickness (1–8mm), a rust-resistant 420 stainless blade, and a safer-feeding approach for faster meal prep. It’s also appealing if you care about cleaning being straightforward thanks to one-click disassembly and dishwasher-safe parts.

You may want to skip it if you dislike reading manuals or you’re the type who needs zero learning curve. The tool is designed for efficiency, but you’ll still need to use the feeding port and handle correctly to get consistent results.
