I bought this trimmer just after seeing its specification, no other valuable brands offer this type of quality in this price range like panasonaic. It has 20 lenght setting from 0.5mm to 10mm to give extraordinary look to your beard, It has a battery backup of 45 minutes after charging 10 hours, so in charging you can use it for months. Works in dry condition also, you can also wash its blade with water not many trimmer have this feature . I am using it from 1 year with no problem, flowless cutting of hair. Go for this product.
