I just received a shipment of the new 2009 Pinnacle Soloist sets this evening....and GSI fixed the issue with the lid on the 14 ounce mug! Yay!
The new thinner, semi opaque mug is better designed (and did I say LIGHTER?) and the lid to the pot lies upside down perfectly on it, making a sippy lid that doesn't pop off.
This set just got a whole lot better (and off topic, the pot is now non-stick lined as well).
