If you want to cook more food in one air fryer session without buying a bigger appliance, choose TQEONKL 3PCS; if you need to fix a wobbly, rattling or scratched glass crisper tray on a Ninja Crispi or COSORI Dual Blaze, choose iAbler 12. These two kits share an aisle but almost nothing else. One adds cooking capacity. The other restores a part that quietly wears out.
• TQEONKL 3PCS — biggest strength: three stackable 8-inch 304 stainless steel racks that turn a 4.2QT–5.8QT air fryer into a multi-level cooker and lift food out of its own grease.
• TQEONKL 3PCS — biggest trade-off: it is a cooking tool, not a repair part. It does nothing for a tray that already wobbles, and it is sized for round 4.2QT–5.8QT baskets, so larger or non-round models are out.
• iAbler 12 — biggest strength: a 12-count set of food-grade silicone bumpers rated to 536°F (280°C) that cushions a glass tray, cuts rattling and replaces lost or hardened factory feet.
• iAbler 12 — biggest trade-off: it is model-specific. It fits Ninja Crispi 4QT glass crisper trays (FN090, FN091, FN100, FN101, FN103) and the COSORI Dual Blaze 6.8QT — nothing else, and it adds zero cooking space.
• Who each pick is for: TQEONKL for the cook who wants more food per batch and less oil on the plate; iAbler for the owner of a supported Ninja or COSORI whose tray has gone noisy, loose or scuffed.
The core idea here is vertical space. Instead of one flat layer of food, you get three round racks, each 8 inches across, made from food-grade 304 stainless steel. Because they stack, you can run one tier for a small side or all three for a full meal — wings on the bottom, vegetables in the middle, something quick on top. The description also notes a mesh-basket design on each rack, which matters more than it sounds: food sits in a shallow basket rather than balancing on open bars, so pulling a rack out does not send dinner onto the counter.
The second half of the pitch is airflow and grease. The regular grid is built to let hot air move around the food instead of pooling under it, and the mesh lets excess fat drip away instead of soaking back in. If you are cooking bacon, sausages or breaded chicken, that separation is the whole point — it is the difference between "air fried" and "fried in its own drippings."
Who should buy it: anyone with a round 4.2QT–5.8QT air fryer who regularly cooks for two or more, wants to batch fries and protein together, and would rather not own a second appliance. Anyone who grills outdoors, filters oil or steams will also get use out of it beyond the air fryer.
Who should skip it: owners of large-capacity or non-round air fryers, anyone whose real problem is a damaged tray, and cooks who only ever heat a single portion — three racks would just be extra washing up.
iAbler 12: Who It's For
This one is a maintenance kit, and it is honest about that. The 12 silicone bumpers are designed to snap into the holes on the rim of a glass crisper tray, replacing the small rubber feet that wear out, harden, melt or simply go missing. They are made from BPA-free, food-grade silicone and rated to withstand temperatures up to 536°F (280°C) without melting or deforming — comfortably above normal air frying conditions.
The fit is narrow and clearly stated: Ninja Crispi Air Fryer 4QT Glass Crisper Tray models FN090, FN091, FN100, FN101, FN103, plus the COSORI Dual Blaze 6.8QT. If your model number is not on that list, this is not your part. Each bumper measures about 0.54" x 0.54" x 0.35", which tells you these are small, round inserts rather than full replacement feet — you push them into the designated holes, tool-free, in seconds.
What you actually get for your trouble is quieter, steadier cooking. The bumpers sit between the glass tray and the metal basket, so they absorb friction and vibration. In practice that means less rattling through the cook cycle and less chance of the tray sliding or scratching the basket. The 12-count is the other quiet advantage: most kits ship eight, and this one gives you spares, so a single lost bumper does not send you shopping again. Cleaning is easy — pop them out, rinse them, or run them through the dishwasher. They are flexible and resistant to tearing, so reinserting them repeatedly should not chew them up.
Who should buy it: anyone with a supported Ninja Crispi or COSORI Dual Blaze whose tray has become noisy, unstable or scratched, and anyone who wants spares on hand before a bumper disappears down the drain.
Side-by-Side: Which Should You Choose?
• Best for cooking more food at once → TQEONKL 3PCS. Three stackable 8-inch racks versus a set of small inserts.
• Best for a noisy or wobbly tray → iAbler 12. Cushioning and stability are exactly what the bumpers are for.
• Best for grease separation → TQEONKL 3PCS. The mesh racks are designed to let fat drip away from the food.
• Best for exact-model compatibility → iAbler 12, provided your model is a Ninja Crispi FN090/FN091/FN100/FN101/FN103 or a COSORI Dual Blaze 6.8QT.
• Best for broad air fryer fit → TQEONKL 3PCS, which is listed for 4.2QT–5.8QT round baskets.
• Best for heat tolerance on paper → iAbler 12, with silicone rated to 536°F (280°C); TQEONKL relies on 304 stainless steel, which is built for air-fryer temperatures.
• Best for dishwasher convenience → a tie. Both are dishwasher safe.
• Best for long-term ownership → iAbler 12. Twelve bumpers means spares for years of maintenance.
In my opinion, most people searching this comparison should buy the TQEONKL 3PCS. It changes what your air fryer can do — more food per batch, better air circulation, less grease on the plate — and the stainless steel racks, clamp and brush cover the whole workflow. The iAbler 12 is excellent at a much narrower job, and if your Ninja Crispi or COSORI Dual Blaze tray rattles or has lost its feet, it is the more useful purchase of the two. But that is a repair, not an upgrade. If you only have budget for one and your tray is fine, go with TQEONKL.
FAQ
Only if it is a Ninja Crispi 4QT glass crisper tray in models FN090, FN091, FN100, FN101 or FN103, or a COSORI Dual Blaze 6.8QT. Check your model number first — the bumpers are shaped to snap into those specific tray holes.
No. TQEONKL adds cooking capacity and grease separation to a 4.2QT–5.8QT air fryer. iAbler replaces worn rubber feet to reduce rattling, improve tray stability and prevent scratches. One cooks, one maintains.
