This is the best air cooler in 2018 as it has advanced features. I have bought this 2 months ago. Its working pretty so well. It has a intelligent sense cintroll like if u wave left at the top u can controll the speed and if u wave right u can controll cool fuction and if u hold ir hamd on the top u can even set the timer. It is best as it has intelligent honeycomb technology which ensures beter cooling effect. It has air purifier as well as bacteria purifier inbuilt. It has 2 years of warranty and even its a trusty company.
