Boy, those are nice.
You get what you pay for.
I noticed that the front top corners had taken some damage. Even without use but the stoves still look durable.
The fire lighting technique is commonly done in other stoves by having a bit of vented ribbing along the bottom. Strengthens the bottom too. That works especially well with the air being supplied from higher where the air gets heated before. More efficient combustion.
That tech costs because its work plus materials and would make these really expensive.
Most people don't consider stoves because they like the view of the fire.
You can get warmer with a stove than an equivalent sized open fire.
Efficient. Use less wood. Less impact.
Lungs and eyes take in far less smoke with the flues.
Use in tents with some rules.
Warm or cook on easier and cleaner than a fire grate.
Safer because a 3 inch fire pan lip doesn't stop sparks like a spark arrestor.
Stoves can extend the heat.
Cost and a big negative is you'll get friends. Too many friends.
Boy would a sheep herder have died for one of these.
