Query: Ouch, this hurts!

it may just have been me and not knowing how to use this but I found that this was not a relaxing experience. The massager came compacted and you have to manually seperate each metal arm, and then when I tried to use this it jabbed into my head. I tried adjusting the arms a little and it still was very uncomfortable. I would, and do stay away from this now. Not the best purchase I have ever made.
