A:Answer Our BestBuy sales rep, who seemed to be knowledgeable, stated that there was a production stop/start to address signficant defects. We were told this when we were hesitant to buy because of all the poor reviews. We were assured the unit we would be buying in May, 2019 would be the "updated" model. However, our model makes a loud buzzing sound when running which is way above the acceptable decibel level, and its frequency is disturbing to me, and the fact that I can hear it running 30+ feet away. AVOID THIS UNIT/BRAND. Do you really want to buy something that was so poorly designed or built that they had to stop the production run? Don't make our same mistake.
