Now I bought this thing back in Jan 2017 for my Dad. I thought it’d help him clean shave his beard but it didn’t. This is just a trimmer, not a shaver. This trimmer comes with two external blades of 6mm and 9mm. For me the 6mm blade would easily get connected and removed, whereas the 9mm blade connects easily but is tough to remove. Now talking about the design of this blade, its pretty good not not that attractive. This trimmer works on single pencil rechargable cell which comes with the trimmer itself. It does trims your facial hairs but still very extreme shorts hairs doesn’t get trimmed. The one thing that I found about this trimmer is that it needs that cell only needs to be highly charged to make the trimmer work. Once I removed the primary blade and turned on the trimmer, the motor was rotating fast inside but it couldn’t move the primary blade
