I have been using this voltas WAC 183 DX since three years and it is working really well.The main features which I liked about this air conditioner is the’wave of air’ it cools the room is just 10 or 15 minutes and biggest feature I liked in this air conditioner is the turbo feature. Whenever we feel hot or we want our ac to cool more than button turbo is the best option. Whenever I turn on turbo button it cools so well and cools the room is just 5 or 10 minutes.Another feature which I really liked about this air conditioner is the 1 hour off feature. When we want to cool our room for just 1 hour, the hour off feature is best option, after pressing the 1 hour off button on the rc the ac will cool for 1 hour then after that it will turn off automatically after 1 hour of cooling.
