Hello guys today I am giving review on nova nhc 3921 trimmer . I have personal experience of nova trimmer because I had bought it 3 to 4times from flipcart . well at starting its works good you have to cahrging it for 3 to 4 hrs and it gives you perfect trim but after 2 or 3 months it become slow and takes too much time for charging and it has cap for reducing number of blad its cap is very weak it can be crack if you more push it . and after 6 months its totally become useless because bettery will doesn’t work and you can not charging also, its only become warm if you put in charging . I had bought 3 trimmer and all were become useless . its price were almost 300 and by shopping online I had pay extra 50 rs so if you want to use for only 2 to 3 months you can take it and if you want to use long time so I suggest to take higher price trimmer of rs 1500 to 3000 it can work for long time .thank you.
