I have a go-to vibrator. I use it for my version of a deeply pleasurable solo quickie as seen in this video. It's the Rechargeable Magic Wand by Vibratex (accept no imitations— lots of counterfeit toys out there). Originally created by Hitachi, the Magic Wand is an intensely powerful vibrator. The Rechargeable version allows you to go cordless and has 4 intensities and 4 patterns. I purchased mine at venusenvy.ca (an award-winning sex shop and bookstore) that I highly recommend for online sex toy purchases. Not an ad— I just like to share my shopping experience.
