I have this vibrator that which i've gotten from Japan
It has multiple speed and settings, women usually can't handle the highiest speed
It doesn't have a brand to it, but it had been my secret weapon for quite some time
I had some girlfriends who swore by putting an unbalanced load into the washing machine and mooching up to it and grinding with their pussy while it was on spin cycle - and you get a load done at the same time!!
I find that i get the best from any vib by connecting it to a transformer with a higher voltage. It really zups them up and they dont go flat at the wrong time and they really help me to spurt my husband loves it!!
