Until recently: the stoves were cracking badly and falling apart after a short while. This was due to several poor production techniques. After giving this problem some thought, a new way of doing things was implemented. Of course, every stove is made to be better than the previous stove in some way. Every little thing that can be improved upon in some way is striven for. The end result is a better product that doesn’t show significant cracks! Plus, the stoves are now also better at insulating and channeling heat, and LIGHTER!
Moral of the story: The more you put into it, the more you get out of it.
The thermometer reads: 923.3°F inside chimney
