If you watch his body language he was definitely tense, but he stayed calm. He backed up a few times when I held it near his nose at first (it has a really quiet buzz that sounded like a bee or those bot flies, so he didn't like it), but he eventually stopped even doing that. Since he was tense I only played with them for about two minutes. I want to keep the sessions short and sweet. The bad news is the clippers are so dull they wouldn't cut his hair lol. I really didn't feel like using scissors so his mane will stay as it is for now. :)
P.S. Sorry for the cell phone video. Since my camera is dead you'll have to put up with cell phone pictures and videos for a while.
