Hi friends today I am going to share information about this trimmer named as Nova trimmer. I had purchased this trimmer around two weeks ago from the online and according to my suggestion .you should not buy this trimmer as it is not good as much its looks. its battery gets down within five minutes of continuous charge . so it became a very problem to charge whenever you are in hurry. I think its just waste of money and time for the customers. we get only one blades for it for zero size I prefer you to take another company one to get different size of blades . it is not much effective as I already said within five minutes of charge it stopped its battery gets down. so I suggest you to buy another product.
