Summary of "The Internet's Favorite Non-Toxic Air Fryers Have One Problem"

Video focus

Hands-on review and stress testing of the Ninja Crispi (original) and Ninja Crispi Pro glass “non‑toxic” air fryers. Over 100 meals were cooked across both units and they were tested head‑to‑head against six other highly rated air fryers.

Main features

Cooking vessel: thick borosilicate glass containers (marketed as “non‑toxic”).
Food contact surface: removable aluminum crisper plate with a nano‑ceramic (Teflon‑free) coating.
Ninja Crispi (original): heating unit lifts off the glass container; no exact temperature setting—operates by modes with temperature ranges.
Crispi Pro: fixed heating element; adjustable base height for different container sizes; exact temperature control from 80°F–450°F in 5°F increments.
Glass container is dishwasher‑safe and can be used to cook, serve, cover, and store leftovers.

Performance (tests & results)

Test scope included fries, cookies, squash, wings (same settings across models); measured noise at air fry mode 400°F; removed crisper plates 100×; shook baskets; and ran thermal shock tests on the glass.

Fries: crispy and even in ≈10 minutes.
Wings: under 25 minutes in the Ninja Crispis with crispy skin and juicy meat.
Cookies: in the Crispis they browned too quickly on top before the bottom finished (less even than some competitors).
Butternut squash (Crispi Pro): outside browned faster than the interior softened — required lowering the temperature mid‑cook.
Reheating: crisps food quickly without drying it out.
Noise: Crispi Pro was the loudest model tested; the original Crispi was noticeably quieter. The Ninja DoubleStack is also loud (two fans).
Comparison highlight: Typhur Dome 2 was fastest for wings (≈18 minutes) and produced the most even cookies due to top + bottom heating elements.

Design, size & handling

Real cooking surface is small: crisper plate is about 8 × 8 inches across all container sizes. Capacity increases vertically, not horizontally.
Fits roughly four overlapping slices of bread or ~10–11 chicken wings without stacking — better suited for 1–2 (up to 3) people; smaller usable area than many competitors (e.g., Instant Vortex, Typhur).
Weight: large glass container ≈4+ lb; Crispi Pro total ≈5+ lb. Traditional aluminum baskets are ~2.5 lb.
Handling: the Pro requires two hands and careful alignment to slide under the fixed heating element, making it less convenient than a typical pull‑out basket.
Original Crispi: heating element lifts off and must be set down (potential counter hazard if set on flammable materials). Air vent placement under the power cord blows hot air on the cord — a poor design choice.
Glass and nearby plastics get very hot and remain hot for 5–10 minutes; handles are manageable but often require oven mitts.

Durability & safety

Reviewer thermal shock tests (hot→tap, hot→ice, freezer→hot) did not shatter the glass.
There are documented (rare) reports online of glass shattering, likely caused by preexisting chips or hairline cracks — this represents a meaningful risk.
Ceramic plate coatings can scratch and flake over time (same risk as other ceramic‑coated air fryers), but the glass design reduces total coated surface area near food.
Plastic base is permanently attached to the glass with a small gap that’s hard to scrub and dry — a cleaning limitation.

Pros

See‑through glass lets you monitor food and stop/flip at the right moment without losing heat.
Good overall cooking performance — fast and consistent for many foods.
Dishwasher‑safe glass and containers that don’t retain odors.
Crispi Pro: precise temperature control (80–450°F in 5°F steps) and fixed heating element improve usability.
Reheats food well without drying.

Cons / major problems

Small horizontal cooking area (~8×8 in) despite the Pro’s 6‑quart labeling.
Heavy glass containers; Pro is clunky to handle and usually requires two hands.
Original Crispi’s lift‑off heating element is inconvenient and can be unsafe if placed on flammable surfaces; vent placement blows hot air on the power cord.
Glass gets extremely hot and there are rare but real reports of shattering.
Cookies and some foods may require frequent adjustments versus best‑in‑class models.
Ceramic coating can scratch/flake (similar risk as other ceramic‑coated models).

Comparisons & alternatives

Typhur Dome 2: top performer — dual heating (top + bottom) yields faster wings (≈18 min) and more even cookies; wider cooking surface. Recommended as the best alternative (but more expensive).
Instant Pot Vortex and COSORI TurboBlaze: cheaper, high‑performing alternatives with larger usable cooking surfaces.

Reviewer’s verdict / recommendation

Original Ninja Crispi: not recommended for most home cooks due to the lift‑off heating element, limited horizontal capacity, and heavy glass construction.
Crispi Pro: preferred over the original — better temperature control and fixed heating element; reasonable for 1–3 people if you accept the glass‑break risk.
Main caveat for both models: documented glass shattering reports are a significant concern. If you’re not willing to accept that risk, choose another model (Typhur Dome 2 recommended).

All unique points mentioned about the product

Food cooks in a glass container but actually sits on an aluminum crisper plate with a nano‑ceramic coating.
Ceramic coating is Teflon‑free but can scratch/flake like other ceramic coatings.
Less coated surface area surrounding food compared with fully coated baskets.
Original Crispi has a lift‑off heating unit; Crispi Pro has a fixed element with adjustable base height.
Crispi Pro allows exact temperature control (80–450°F in 5°F increments); the original only offers mode ranges.
Ability to see food through glass reduces the need to open the basket and lose heat.
Fries and certain foods cook fast and even (fries ≈10 min; wings <25 min).
Cookies tend to brown on top too quickly in both Crispis.
Butternut squash may brown outside faster than the interior softens — requires temperature adjustments.
Reheating works well — crisps without drying.
Crispi Pro is the loudest air fryer tested; original Crispi is quieter.
Real cooking surface is only ≈8×8 inches across all container sizes — capacity increases vertically, not horizontally.
Can fit ≈4 overlapping slices of bread or ≈10–11 wings without stacking.
Glass containers are heavy (>4 lb for large container; Pro >5 lb); two‑hand handling is needed for the Pro.
Original’s heating element must be set down after cooking — can raise surface temperature and poses fire risk if placed on paper/etc.
Air vent placement under the cord on the original is a design flaw (cord blasted with hot air).
Glass and nearby plastics get very hot and stay hot for minutes after cooking.
Glass passed the reviewer’s thermal shock tests, but rare shattering incidents are reported elsewhere — likely from existing damage.
Glass containers are dishwasher‑safe and don’t retain odors.
Plastic base is permanently attached to glass with a small gap — difficult to fully clean and dry.

Speakers / perspective

Single reviewer/narrator (Prudent Reviews) provided the test methodology, performance metrics, design observations, safety concerns, and final recommendation. (A sponsor mention — Laundry Sauce — was included in the video but unrelated to the product review.)

Concise takeaway: The Ninja Crispis cook well and the glass lets you monitor food easily; the Crispi Pro adds precise control and better usability. However, limited horizontal capacity, heavy glass construction, clunky handling (original especially), and a real—though rare—risk of glass shattering make the original Crispi a poor choice for most people. The Crispi Pro is reasonable for 1–3 people if you accept the glass risk; otherwise consider the Typhur Dome 2 (best performer) or solid budget options like Instant Pot Vortex or COSORI TurboBlaze.
