I recently bought one and am very happy with the purchase.
As you said it’s basically an oven replacer. I would say it’s a bit better I would say and also a lot faster.
Preheating happens in ~2 minutes and you’re good to go, and it’s big enough.
I got the Cosori, it even has an app so you can control it from your phone and it give you notifications with the status.
