This is my favorite estim toy. It's the perfect size for someone experienced in anal play because it creates very smooth sensations. I've found smaller toys like the large egg is less pleasurable and more painful, but this one was fun from the beginning, and I've been able to experiment with different settings more with the Stuffer than any other plugs I've tried from MyStim or Electrastim...mainly because the design focuses the stimulation and the sphincter that is naturally erotic.
