DEFY Microwave that becomes a SWIMMING POOL after use (DMO 390)

Your Defy DMO 390 has to be the WORST Microwave that I have ever owned! My 'Cheapie' ( KIC ) that I owned way back in 1992 was FAR superior to the Defy that I recently bought. I have owned a Bauknecht, and a Samsung and NEVER had an internal Condensation problem as with the Trashy Defy that I now have. What was the design department doing when they designed this LOUSY microwave..... Trying a new swimming pool?? I now see why Defy has ADDED a Sticker on the front inside to dry the thing out now..... it's clear to acknowledge their *****-up'!!!
