I had this trimmer for last one week. it shows numbering like 0.2, 0.4, 0.8, 2.0 but cut hair same for every number I supposed that 2.0 will cut quite bigger than 0.2 but cutting same. while cutting hairs I observe hairs still as it is after trimming also. this trimmer did not cut hairs in a single swipe. I wasted my half hour for my shaving only because of this trimmer. I had rashes on my face due to this trimmer
