I can say that Samsung provided me AC inverter at high cost with poor quality. And I got it repaired two times till now, since from when I bought it and I Incured additional cost by repairing it for two times. And I should clean the dust three times in week.And it consumes more power. And I spent huge money till now by repairing it. And I was cheated by description of features. So my suggestion is not to purchase by simply seeing features. Make enquiries and purchase the product. And don’t purchase this product.
