I brought this trimmer thinking that it is the best trimmer.but all my expectations went wrong.it has got both charging and battery options.but its battery is of no use.even its charging is not standing for long time.and also it is taking so much of time to get charged.its blade also irritates our beard.insted of trimming it is catching my beard.it hurts when it does happen.it is not at all a trusted product.it is a waste of money.correctly it worked only 2 weeks perfectly.later it is good for nothing.totally this product is a waste product.friends dont by nova trimmers.i dont recommend thus product.
