Need Vibrator advice! Quick!!!

I've searched high and low for this special vibrator used in Indian head massages but I'm a first time user.  Any advice on where to buy online?  I'd like one that's quiet with multiple speeds, has long battery life for use while travelling and different pulses........really relaxes me after a long, hard day.  Will be in the US in a week for R&R so I need to decide quickly!!  This vibrator will be the only thing I miss about India   Have you used before?  If so, what's your favorite?

I am not aware of that. My mom bought several of these things at Dollar Tree. They look like an open whisk. You put them on your scalp and masage it. She gave them to my brother and I for xmas. Along with his two older children. She was trying to be clever by putting money inside with them. We laughed and told her how they could be kind of dirty. The funny part is my 8 year old nephew thought it was cool and wanted one so he took my brothers. Oh also maybe a rabbit would work?

I've never heard of it but if you do find it let me know.

Sorry, I have a few different vibrators (each special in their own way  WINKY FACE), but I'm not familiar with the Indian head massager. I'm intrigued, though.

Is the Indian head massager long and cylindrical, or is it more in the shape of a ball?  I have no idea what it is, but I'm picturing a chain of vibrating balls that you drape over your head.  Am I even close?

I can only find pictures of hands when I google "Indian Head Massager":

But when I changed it to "Indian head vibrator", ooooh boy! Lots of fun stuff, but I like this one:

Amazon sells this one

This one looks a little intimidating to me.

That looks way too scary!

I found a picture but can't insert it.  It's called a WeVibe4/
