Warning to all . Don’t buy Kent . They have given the service to one local dealer who takes you for a ride . The dealer in chennai is worst . The app does not work and when they come for service they tell u it is not covered in warranty. Worst service . They talk very rough too ..they even close the case without doing the service . Don’t know how can they do it .You cannot call customer service too . The failure rate is High when compared to aqua guard .
