I purchased this trimmer online and believe me guys it was the biggest mistake of my life. The description of the product on internet was like its the best trimmer but after using it for some days I realised that cheap products of nova can never remain stable for long period. The battery life of the product is very less. I have to charge it for 10 hours and it results the usage of only 45 minutes that too also in very few cases. Also we cannot use the product while charging. Its a low quality product and doesn’t maintain the value of our money. I used this product only for 1 month that too facing some difficulties regarding the quality of the product. I would recommend all the users not to prefer cheap products of nova.
