I have one of their conicals. I hated it. Used it twice. Waste of money. For one thing you have to buy a separate seal to seal the lid down, otherwise you are just resting the lid loosely. Also, the valves are not sanitary and you can't take them apart. That works fine on a boil kettle but you want to be able to clean you valves after every brew (or at least every 2 or 3).
As far as their MT I'd just stick witha cooler, personally.
