I wouldn’t call it a bad decision to buy this A.C, It has some pros and some cons to it. It has a good cooling system, it can cool down a medium sized room in 10 minutes or so. Another good thing is that it makes no sound or a very less sound. The one thing it lacks a big time is energy saving, yes it consumes a lot of electricity so it might put some extra burden on your pocket. It is durable and with proper maintenance it can last and work just like new for quite a long time.
