I got this philips trimmer as a gift almost two years back. Since then I have been using it regurarly and completely dependent upon. I have not experienced any lags or problems with it. It is very convenient to charge and also gives a decent backup when charged fully. It is simple to use and easy to clean.
This comes at a price range of approx 800 rupees to 1000 rupees and I must say it is very much value for money.
