Worst trimmer I have ever used, this trimmer is not even doing its job properly. It pulls beard or moustache hairs badly which causes flow of blood.
Charging time of this device is more than 10 hours and after 100% of charging it runs only about half an hour. The material used to make this device is of very low quality plastic and does not even have proper finishing ended up looking like a fake or chinese thing. The charger given with this nova hair trimmer is also of very low quality and slow. I strongly recommend you to not to buy this product from nova.
