I am using nova advance NHT 1047 trimmer since 1 month.but after some time it doesnt work well. I bought it from snapdeal, There is a problem of charging trimmer. It discharges quickly within 15 minutes & it takes around 3 hours to charge completely. It is under warrenty but contact number & email id given on box is not working. There is problem in its blades too because it does not trim proper. So I am suggesting that while buying nova trimmer please check charger & blades & ask for proper contact number, email id for queries.
