There is a removable non-stick grilling surface that is a lot harder to clean than the non-stick surface you would encounter on a frying pan.

Yes, the burgers have a tendency to fiercely glue themselves to the bottom of the frying pan -- and yes, it's been an "experience" trying to chisel them off, hopefully as intact as possible.

So basically you'd get the same effect if you just used a frying pan on the stove top

It's possible that using a lower cooking temperature will mitigate that effect but even if it does you should expect to be grilling meat for a much longer period of time than an outdoor grill, grilling over a stove in a frying pan or using something like a George Foreman Grill (do they still make those?) would take

Genial y compacta me encanto

My photo shows Kobe beef burgers, which tasted and looked just as great as if they were grilled outdoors inside my smoky barbecue

Turn on high to preheat for 5-10 min, it does take mostly the full ten minutes to really get as hot as it can
