I just received an email from Oglesby & Butler regarding the melting mouthpieces.... "Thank you for your emails. After extensive analysis and investigation of your feedback, we are responding to the situation by replacing the plastic mouthpiece connection with stainless steel.
We will be sending you a replacement shortly. Thank you for your patience and understanding."
I had sent my unit over for repair a couple weeks ago. Today I got about the same email. It also said they expect to be sending it out between 19th and the 23rd.
