We had one and used it a fair amount before I dropped the insert thing on the floor, which dented it into non- functioning.
I don’t recall what the size category was but it wasn’t large - medium, small? Not super small.
We used it mostly for veggies- acorn squash slices, eggplant, broccoli or Brussels sprouts, that kind of thing. Some frozen sweet potato fries.
I know I liked it at the time for being able to not heat up oven, runs on a timer so can check & add more time. But, it really didn’t hold the amount of veggies we can consume at supper, & I didn’t feel it was so great if I had to do 2 batches. It came with a small grill insert to keep things higher, more are circulating, & I used a few times for some chicken parts or something.
I considered replacing it but it seems I would need a big one , then still wouldn’t use every day. I downsized house yet actually have a bit more useful storage in or near kitchen yet still not motivated, now 2+ years after losing it. Despite having to heat up oven I can do bigger batches or different timings of things on more than one pan, or a “ sheet pan” recipe, or most nights I do stovetop sauté of foods even veggies ( or eat raw) so I doubt I’ll get another.
