I want to share my experiance of kenstar 40 wondercooler . I have used many collers . I have used around six to seven coolers .kenstar 40 is beat in compair to other coolers so I suggest you to go for it and if you want good quality at lowset rate you should buy this one only . I am using it from three months daily but there is no single defect in this cooler . it is very rear thing so I will give five star to this cooler and service and support is very good so I will give five star to service and support
