O-General Is a royal air conditioner which will cool/chilled your room in 10-12 mins, U will find urself very happy after buying this product. I purchased this because I trusted this brand as if for a.c. I loved its service and easy to use feature. the a/c cools 300sqft area in few minutes which was not being done by other a/c so I chose this brand as my primary choice. its on the costlier side but its worth buying it.
