Ninja Crispi vs Our Place Wonder Oven — Which Non-Toxic Appliance Should You Buy?
The Ninja Crispi and Our Place Wonder Oven aren't the same type of appliance — one's a glass-container air fryer, the other's a multi-function ceramic-coated toaster oven — but they solve the same underlying problem: a non-toxic, premium countertop cooking appliance, at almost the same price ($152.95 vs $185.00). Here's exactly where each one wins.
Best if you want glass containers that double as fridge-safe storage, and a more honestly sized appliance for the price.

💰 Price
The Ninja Crispi ($152.95) and Our Place Wonder Oven ($185.00) are within $5 of each other — close enough that price alone shouldn't decide this for you.
Verdict: Tie — $5 apart is negligible
⭐ Rating
The Ninja Crispi holds a 4.6 rating versus the Wonder Oven's 4.3. Ninja has a longer track record in the glass air fryer space, which likely contributes to the gap.
Verdict: Ninja Crispi — higher rating
⚙️ Cooking Functions
The Wonder Oven is the more versatile device on paper: 6-in-1 (air fry, bake, roast, toast, grill, reheat) versus the Crispi's 4 (Max Crisp, Bake, Air Fry, Recrisp). If you want one appliance to replace your toaster and your oven broiler, not just your air fryer, the Wonder Oven covers more ground.
Verdict: Our Place Wonder Oven — more cooking functions
🧊 Storage & Meal Prep
This is where the Crispi's design actually wins for a specific use case: its glass containers go straight from the air fryer to the fridge to the microwave, with the same lid, no transferring food. The Wonder Oven doesn't have this — its interior is fixed and ceramic-coated, built for cooking, not for storage.
Verdict: Ninja Crispi — unique fridge-to-microwave glass system
🏺 Non-Toxic Approach
Different philosophies, same goal. The Crispi avoids the coating question entirely with PFAS-free glass containers — nothing to coat, nothing to wear off. The Wonder Oven uses Thermakind, a proprietary ceramic non-stick coating verified PFAS and PTFE-free. Glass is the more inherently non-reactive material long-term; a verified ceramic coating adds cooking convenience (things release without oil) that bare glass doesn't offer as easily.
Verdict: Tie — both are genuinely non-toxic, different trade-offs
📦 Capacity & Accessories
The Wonder Oven's 13qt interior sounds much larger than the Crispi's 4Qt, but several reviewers note it still runs small for a family of 3-4 in practice — and extra accessory kits cost $49 or more on top. The Crispi's 4Qt main container plus a smaller 6-cup container is honestly sized for 1-4 people from the start, with both containers included.
Verdict: Ninja Crispi — more honestly sized for the price, no extra accessory cost
🤔 The Real Question — What Are You Actually Trying to Replace?
These two products get compared constantly, but they're not really competing for the same job. If you're mainly air frying and want to cut plastic containers out of your meal-prep routine, the Ninja Crispi's glass-to-fridge system is the more complete solution — nothing else in this comparison replicates it.
If you're trying to replace a toaster, a small oven, and an air fryer with one non-toxic countertop appliance, the Wonder Oven's 6 functions cover more ground, and Thermakind gives you a verified PFAS-free surface without needing bare glass.
Our call: for straightforward air frying plus genuine meal-prep storage, buy the Crispi. For maximum function count in one box and you don't mind paying more for accessories later, the Wonder Oven earns its higher function count.

Frequently Asked Questions
Is the Ninja Crispi better than the Our Place Wonder Oven?
For most buyers, yes — the Crispi rates higher, is more honestly sized for its price without extra accessory costs, and its glass containers double as fridge and microwave-safe storage, which the Wonder Oven doesn't offer. The Wonder Oven wins specifically if you want more cooking functions (roast, toast, grill) in one appliance and don't mind paying extra for accessories.
Are the Ninja Crispi and Our Place Wonder Oven really PFAS-free?
Yes, through different approaches. The Crispi uses glass containers with no coating at all to worry about. The Wonder Oven uses Thermakind, a named ceramic coating technology the brand states is made without PFAS or PTFE — a verifiable claim, not generic "non-stick" marketing.
Can the Our Place Wonder Oven store food like the Ninja Crispi?
No — the Wonder Oven has a fixed, ceramic-coated interior built for cooking, not a removable storage container. The Ninja Crispi's glass containers are its key differentiator: the same vessel goes from air fryer to fridge to microwave with its lid on.
