I've got the morso squirrel cleanheat, 'ribbed sides'.
Great, well built, sturdy little stove, but if you want the fire to be up and running in the morning, you will be disappointed.
When damped down for the evening, the glass blackens (despite the claims for cleanheat) and the fire has burnt its self out by morning. The chamber is not big enough. But up and running you cannot fault it. Does everything it says it does.
So summing up, if it's for over night running, I would get a bigger morso, but other than that, it's fine.
