See my reply above in the Cookshack Owners Forum.
Our FEC s have been on the circuit all over the southeast for three years and I guess we should carry some spare items,but don't.
I don't know what often means, for breakdowns,but I have a non ramp and a new IQ and have yet to have a second's problem.
I think Rodney/Pellet Envy has posted somewhere on here about how many tons of pellets,how many comps,etc, over the years and he did replace a shear pin-which any hardware store carries.
If you did,there is a Cookshack toll free service,instant help.
Yes,FEC s do burn more efficiently than many cookers,so you don't have to worry about oversmoking,or a creosote taste.
We run ours on a $50 battery and a $30 invertor for the whole contest.
I've known Stump,the developer,for years and they build a popular gravity feed cooker.
I don't know much more ,since they sold the company.
