Nova trimmer is something that can be said as cheap and best. I ordered one from flipkart and have been using it since past 6 months. It is very easy to charge and does its job quite well.
There is nothing better you can find below the price bracket of 500rs.
It wont completly shave off ur beard as razors do but gives you a natural look with facial hair.
One can also buy this product from shops for the touch and feel aspect as Nova has not been that popular brand like Philips but it does give you more than you can expect from such a niche market product.
