I am using this trimmer for almost a year . I feel this trimmer is very good and help full . Their are no compliant with is trimmer till now but the one problem is their is not much battery capacity in this trimmer . And also this trimmer and its charger is very slim by which we can carry it to any were we want . I am a student so I want to travel every month from hostel to home and home to hostel then also it can be kept in a bag no complaints will occur to it . But in hostel me and my room mates use this trimmer commonly then also no complaints are occurring to it . I feel this trimmer is very helpful and user friendly . And also no maintenance are concurring .
