I got a liberator 2 this fall: I burn wood or pellets, depending on my split wood supply.
The grate for the pellets is not showing any sign of corrosion.
There’s a good discussion about the stainless steel grate here, and a lot more information from Sky Huddleston, designer and manufacturer of the liberator 😊.

I recommend the Liberator stove, and see a nicely done thermal mass in some of the photos in this
thread.

Unfortunately I didn’t get a mass built for mine, because I got it so late in the fall.
I may be selling my stove once the heating season is over, because I’ll be selling my house, and don’t feel comfortable leaving it in the house for a person totally unfamiliar with
rocket stove mass heaters. Pass the word along, I will be selling at a reduced price, and someone would have to drive to north eastern California to pick it up.
Pass the word, and drop me a pm!
