Their own specs dont indicate that they are particularly light, short, or quiet but also not awful at any of those things, just a bit off from market leaders at this time. AL construction is also a bit different for cans made in the states but seems very typical abroad.
Might be worth it depending on what kind of deal you get. I'd probably be more prone to getting an AB A-10 or other steel can in that $500 price range but maybe they'd be solid if you got good deal?
