The Ninja Crispi, a small glass-bottom air fryer that doesn’t usually get much of a discount at Amazon, is enjoying an anomaly deal that brings the price down to $139 — $40 less than its regular price of $179.
The splashiest feature here is not the discount but your see-through, borosilicate-glass cooking bowl that lets you watch food crisp up without shattering your cover — or leaching away heat.
Why the glass bottom matters for everyday cooking
With most air fryers you can’t see what’s cooking since it’s hidden in a basket. The design traps heat, but it also necessitates guesswork. Pop open the drawer to peek at doneness and you lose temperature, slow cooking time and run the risk of uneven browning. With Ninja’s glass-bottom feature, you can monitor the color and texture of your food in real time — golden wings, blistered Brussels sprouts or a bubbling gratin — without interrupting airflow.
That visibility might seem like a small change, but it alters how you cook. It helps zero in on that narrow moment between “perfectly crisp” and “just a shade too dark;” aim for there, because that is where many air fryers go off the rails. Testing groups, including Consumer Reports, have observed that uniformity is a frequent pain point among basket-style models; a viewing window enables you to course-correct on the fly.
What you get in the box with the Ninja Crispi
Ninja includes two thermal-glass bowls — a 4-quart for mains and family sides, and a 6-cup that’s better suited to small snacks or reheats. The system accommodates air fry, bake and reheat modes, as well as Max Crisp — Ninja’s high-heat, high-airflow setting that replicates broiling for ultra-crunchy results with frozen fries or breaded cutlets.
By design, tight quarters support speed in the smaller bowl — say a fistful of leftover fries or roasted veggies in about as much time as it takes to set the table — while the 4-quart bowl offers space for a whole chicken with root vegetables. Low preheat time, coupled with superior heat distribution, brings the oven to temperature quickly for each baking demand.
Materials and safety details for the glass bowls
The bowls are crafted from borosilicate glass, the family that includes labware and many premium bakeware lines, chosen for its thermal shock resistance. That means it’s engineered to better withstand rapid temperature changes than plain old soda-lime glass. Both bowls are dishwasher safe, and that’s a more important quality-of-life improvement compared to scrubbing mesh baskets.
Ninja has protective feet, so feel free to place it on granite, tile or wood countertops; just don’t rest it on plastic and be sure to let air circulate beneath the base. The U.S. Consumer Product Safety Commission recommends having clearance around items that generate heat — just good advice for any air fryer.
Performance and efficiency in real-world cooking
Air fryers move hot air around aggressively in a small chamber, which is why they provide crispy exteriors that need little to no added oil. Testing conducted by organizations including Consumer Reports shows that in many cases, air fryers outperform a full-size oven in both preheat and total cook time for small batches. The Department of Energy typically recommends using smaller appliances if you’re cooking for just a few people, which is where most compact air fryers really shine anyway.
Real-life examples confirm this: wings, breaded tofu and frozen snacks form a crunchy crust under Max Crisp in no time, while roasted vegetables take on a golden color without getting super soggy. You can also watch the browning unfold through glass, helping you pull food at peak texture; there is no more overcompensating with an extra two minutes “just in case.”
Value versus alternatives at this discounted price
At $139, the Crispi comes in for less than many of the midrange models from brands like Instant and Cosori with similar capacity — and far cheaper than an oven that can also broil, dehydrate or cook a 12-pound turkey. It gives you a clear view of your food compared with air fryers that simply add a small window to an opaque basket. Price trackers like Camelcamelcamel have indicated that this category has bounced around between promotion pricing and list pricing; catching a $40 reduction on the newer, glass-forward design is not insignificant.
If you value easy cleanup, a clear view of what’s going on inside, and a small footprint that can accommodate weeknight mains or sub in for more traditional grilling, the Crispi’s package is compelling. And its dual-bowl feature expands its capabilities — small-batch reheats will be powerful, and the 4-quart bowl accommodates family meal time.
Bottom line: is the Ninja Crispi deal worth it?
The Ninja Crispi has a simple concept (let the cooks see what’s happening) executed well with sturdy glass, helpful modes and smart countertop protections. Now on sale for $40 off at Amazon, the Ninja Crispi makes a great high-performance upgrade from an opaque basket model, or a space-saving addition to a small kitchen. Availability and pricing are subject to change, but it’s hard not to see the value in this deal — literally.
