The Hitachi is very good but build quality is not what it used to be. My first one lasted years until Pet burnt the motor out.
I lent my new one to Pet but the top broke off it in under an hour. She carried on trying to make herself come on the broken stub, it was quite pitiful to watch.
Regarding the attachments, I find the curved "G" spot one the best.
I will add some pics to my thread later of the attachment in use.
I prefer the Sybian the best though. After an hour on that you need to be dragged off to save you from further self damage.
Kisses,
Miss Broken Wand.
