After using the Ninja Crispi for weeks, I'm obsessed with its space-saving design. The 6-cup glass container is my go-to for single-serving sweet potato fries (crispy in 7 mins!), while the 4QT handles whole chicken wings effortlessly. That thermal shock-resistant borosilicate glass? Game-changer when I need to reheat frozen pizza directly from the freezer.

The see-through cooking process is brilliant - no more guessing when my Brussels sprouts are perfectly charred. Though I wish Ninja had etched the temperature guides instead of using peel-prone stickers that now curl like bad wallpaper after multiple uses.

Cleaning is a dream compared to traditional basket fryers - just pop the glass in the dishwasher (though I handwash the nonstick grill plate to preserve it). The fixed heat-safe feet saved my quartz countertop when I absentmindedly set down the scorching hot unit.

Major con: At $179, it's pricier than basic air fryers. The preset temperature ranges (no precise dial) frustrated me when perfecting steak doneness - I had to use a meat thermometer. Also, that "portable" claim only works if you're okay carrying what feels like a hot glass brick with dangling power cords.

For urban cooks with tiny kitchens, this justifies its cost through multifunctionality (baking muffins in the morning, air-frying tofu at night). Just know it's more "stationary appliance" than true portable cooker despite Ninja's marketing.
