Je n'aime pas L'AmourThe Thumper is definitely not a toy for someone who doesn't know their body very well. It's relatively inexpensive, but I've had much more success with more expensive, better designed toys. I would not recommend using this toy with a partner because of how unpleasant it can feel if used at the wrong angle, depth, or pressure.
The Thumper is a battery operated rabbit made of high quality silicone with a plastic handle. It has about five inches of insertable length (which is what first attracted me to this toy because I have a particularly deep G-spot), and it has a diameter that's comfortable for even beginning toy users. The clitoral vibrator has two flexible "ears" that provide pinpoint stimulation, but it's nearly impossible to get firm clit stimulation without inserting the shaft painfully far.
The shaft rotates at three speeds. Personally, I prefer vibrating patterns to rotating patterns, so I found Thumper's settings uncomfortable. The clitoral attachment has a variety of pulsation settings that suit most intensity preferences, but to people with less sensitive clits, it may not be strong enough.
I was totally disappointed in this vibrator. Most of my qualms are personal preferences, which is why I've rated it three stars instead of one. I only ever use my Thumper now if none of my other G-spot vibrators are charged.
The deep reach of the shaft is great usually, but in order to get enough pressure on my clit to climax, I had to push the shaft in so far that it bruised my cervix. If you have a very sensitive clit, this probably wouldn't be an issue.
My biggest complaint with this toy is that it is much louder than advertised. I had three roommates when I first got the Thumper, and all three of them could hear it over my music. Fortunately, we lived in the city, so they assumed that the noise was coming from outside the apartment. The rotating motor of the shaft was so loud that it could be heard through closed doors and in nonadjacent rooms.
For that reason, I've never tried the Thumper in the shower. I've read that other people have used it successfully under running water. The battery compartment seems to be watertight, and the back screws on securely enough that I would try it if the volume weren't a concern.
