I am Arindam .I really hate this brand Nova. I dont know why the products produced by this brand are really cheap. I bought it just because it priced very low as compared to other trimmers but now I know how the product really works.The charge is very low even if you charge it for 5 hours it works not more than 10 minutes .If you are thinking of trimming your beard then it’s not good for you I bought this trimmer from Flipkart for rupees 350 but it works really bad. I was using Philips AquaTouch which works really great .I am not at all happy with this product so guys please don’t go for this trimmer and never buy anything from brand Nova
