I have used this product for around one year and I have very difficulty using it.
To operate it is not a very tough task but to use it accurately is very tough. Have to run several time at the same place during shaving beard to make all the hair look with equal length. It is not that effective if you are in a hurry.
The battery too got discharged very quickly and got faulty within 6 months of regular use, had to got it changed.
I paid Rs 1500 for this product and with all the difficulties I have faced, it does not have the value for money.
