It's hard to find anything not to like about this product. When I first read the listing, I was a bit skeptical of the multiple vibrating modes, but they are effective, and can keep the party on the receiving off-balance, as it were. The vibrations vary in intensity; the most intense are quite intense. The remote works well and is intuitive. The design is simple yet visually appealing. The base is large enough to prevent inadvertent disappearances, if you take my meaning. The charging arrangements are unusual but effective. All things considered, it seems very well-made. The reason I only gave it 4 stars for beginners is because it's a bit on the large side. Some beginners might need to work their way up to it. Finally, I will mention that while it is marketed as a butt plug, there is at least one other part of the anatomy - the female anatomy, that is - in which it is also quite effective.
