The design flaws prevent me from using this as it is intended - dual-ended vibrators simply need more insertable length. The fat end however is awesome for size queens like me to be used as a dildo and that same end has provided me with pretty serviceable clitoral orgasms. Using the slimmer end just isn't worth it for any application. While I do like this toy, I gave it 3 out of 5 stars because it mostly fails for the intended purpose - as a g-spot vibrator.
