I have been using LG's 8kg front load inverter WM, bought it 2 years ago. Usage is 6 to 8 times a month.
As compared to our conventional top load WM water, detergent and electric power consumption is considerably less.
Cleans very efficiently, no more stains on cuffs and collars especially of white and light color shirts. Also safe on delicate fabric.
As @HellsGuardian said, only downside is the price tag. But if one considers it's benefits then price seems justifiable.
