I was impressed with the Kissa. In terms of Goldilocks the Kissa was JUST RIGHT! The vibe speed wasn't off the charts, but was more than sufficient enough to get the job done. The nubs/texture is a perfect switch up from your plain Jane dildo/vibe. The sound factor, for me was perfect. It's very quiet! So much so that you could use it with house guests in the next room--you little freak you! ;) Not to mention clean up of this toy is easy breezy. Thank you waterproofing!
