I have used nova it is cheap than other brands available .u get battery chargery, 6mm and 9mm , brush, oil.it is good brand with good qyality .you have to charge for 5hrs then u can contimuously use it for 30minutes.its baldes are sarpws so gives a completw trim.sometime when battery is low .then it gets rough on skin.bt it just ony available at rs 300 only.so it is worth ur money.i give a thumbs up for product .it is purely middle class product
