I have been using nova advance NHT 1047 trimmer since one month .I bought it Rs 499 from Amozon online site but after some time it doesnt work well, There is a problem of charging trimmer. It discharges quickly within 10 to 15 minutes & it takes around 2 hours to full charge. It is under warrenty and try to call custmer care contact which number is given on box but did not pick any one my phone.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.the main problem is charging and blade so pls check before puchase and I suggest you pls don’t buy this.
