The design of this vibe is definitely interesting; it has a semi-realistic design with a very vibrant pink color, which makes the tone of the toy fun and unintimidating (despite its larger size for a vibrator). Sometimes "realistic" toys end up looking kind of grotesque and strange, especially rubber ones, but the pink Hottie definitely has an attractive design, while still looking cute and unique. The only thing I can think of that may be a problem to potential users is its veins and ridged area beneath the head. I personally like these details and their being the same color as the rest of the toy makes them pretty non-distracting, but if you're very texture-sensitive, be aware the pink Hottie has veins extending all around the top and sides of the shaft.
The length of this Hottie comes in at about 5.5" insertable, and around 7.75" overall. His shaft is 5.0" around and is fairly thick for something categorized as a "traditional vibrator." If you're wanting to compare this realistic toy to real men, and statistics are to be believed, this guy really is just about the perfect size if you prefer average-sized men. I love this toy's size; the length and girth are perfectly pleasing without me having to think either "That's it?" or "Oh gosh, there's more?!"
Other than the obvious bulb-like base, I would say this toy is very straight in design. The head is barely flared and not very large, which makes the pink Hottie great for comfortable entry. For anal use, the bulbous end with the large nubs should be more than enough resistance to stop your butt from taking your toy farther than you want it to go. I've used this one several times and have never felt even remotely worried about the possibility; however, everyone's bodies are different so I can't make any guarantees as far as that end.
As far as for whom this toy is best-suited, I'd say anyone between the beginner-intermediate range. His girth may be more than some are bargaining for in a vibrator, but truthfully, this toy is not extremely thick or long; pink Hottie fits safely within the average range in both respects. He is not the easiest to hide, and I definitely recommend removing all batteries between uses! This toy looks like a pink, veiny vibrating cock--not my definition of discreet. However, if you've got discreet storage or simply aren't concerned, there's nothing wrong with this toy, size and appearance-wise.
