Ok I'll redeem myself with a response to the specific OP. My whisper 200 had a major failure after two years in service. Some welds failed. They took care of it no questions asked even though it could have been considered out of warranty and I never did the warranty agreement/registration form (I had it for years before I installed and commissioned it). I always appreciated that, but to hear how they just shut their doors with no notice or warning to their employees, thats BS, screw them.
