scroll down to bottom of page and it explains how it cooks with 80% less smoke. Either way, $300 bucks to cook a piece of meat is ridiculous.
This is nothing more than a remake of 2 very popular table top smokeless grillers.
1. Think Faberware open hearth smokeless cooker of days gone by.
Which btw this vintage Faberware cooker is a real hot item for RV'ers. I sold my parents Faberware on ebay for $65.00 to an RV'er.!

and
2. Ronco Rotisserie. Of TV fame, Set it and forget it!

I actually bought one of these old ones at a sale and used it in my MH!
It comes with a basket that you can put a steak in so you can rotisserie it. Makes a killer tasting grilled steak better than any bbq. Grilled and crispy all the way around and juices just keep basting it and going in the steak! Set it and forget AND NO smoke. I believe they are still available and a new model of it.
