Hi everyone if ur staying single in room and want a air cooler this is the best product to beat the summer for one person it is perfect easy to operate and less eletricity consumption.it is inverter capability seven ltr tank capacity honeycomb cooling medium.Everyone thinks that why should we buy a 4000 rs product has the outside we can get a aircooler around 2400 because it comes with warranty with one year and has a brand name crompton not like aircoolees which are brought and assembled and sold to you I can tell u one think it is best for one person hope you like my review and like it if you like it thanks
