Product review (1 stars): LG does not stand behind their products, avoid!
Will never buy another LG product of any kind.  Constant imbalance errors, and after only 2 years of ownership I'm told repair cost is $500.  LG not standing behind this product, even though this is clearly an issue for many users based on reviews here and on other sites.  I took a risk going with a different brand and I paid the price.  Never again!
