I put off getting the Hitachi, like forever. I didn't like the look, heard it was noisy and is considered old technology. I was so wrong! I got it and fell in love with it even though I had a ton of vibe toys.
I can only use it on "low" as the high is just too intense for me. I have never used it with attachments but it is always in my nightstand, on a long extension cord, always ready to go!
Of note; the Hitachi is kinda an Iconic toy in porn shoots. A very successful and enduring vibe. Also great for body massages!
Go for it!!!
