I have got this from a local gents fancy shop and charged it for 3 hours. I have completed half of my trimming and suddenly it got stopped working again I have charged for 15 min I faced the same problem then I put it in a plug and completed trimming as it is charging.
After a few days the blade started struck into my beard and got irritated and thrown it away. If anyone wants to buy a new trimmer go for a big brand like philips.
