I’d invite anyone to touch the amazingness of my Natori underwear.

Well, OK, just this once.

Almost along the lines of the thread title, I don’t notice any difference in longevity of cheap vs expensive batteries, but I definitely notice a difference in the vibration strength of my vibrator when I use cheap batteries.

This is the vibrator to own: http://eroscillator.com/ It is a precision instrument.
No batteries but a very long cord.
