Obviously designed for anal play while seated, the Rude Boy is also good when lying down despite the adjustment to the penetration angle. If it's new or very well cleaned, the Rude Boy also makes a great G-spot stimulator.
The waterproof design makes it great for use in the bath, but the strong vibrations and solid base will make the tub sing if you're sitting up.
If you're feeling acrobatic, you can even include the Rude Boy in regular sex with your partner sitting on your lap or otherwise stimulating you.

Made of body safe silicone, the Rude Boy has a faint odor to it but doesn't pick up any new ones during use.
The shaft is rigid enough to use easily and supple enough that it will fit most users comfortably.
There is a slight seam running along the mid-line of the body, but it doesn't have any noticeable effect on performance.

The shaft is the same size all the way down, so the toy has a tendency to slip out if you don't hold it in by hand or by sitting on it.
Overall, it's a comfortable toy with a gently pleasing pressure. Although, if used while seating, it penetrates fully and only fully.
One of the best things about the shape is it doesn't scream sex toy. With a moderate skill in lying, you could convince snoopers this is an innocent stress relief or massage tool, which I suppose it is.

Very powerful and a perfect shape for prostate stimulation, you will have to use your hips to do most of the work. If you're more of an in-out kinda guy then the Rude Boy still works, but it's not as good at reaching where it's aimed.
Unlike some powerful toys, this uses a single N size battery, which comes with the product. It feels so good you'll barely use any power in a session.
One issue with the controls stands out. They consist of a single on/off button conveniently located right behind your scrotum. This is a fairly stiff button to press, but it does transfer some vibration to the root of the penis.
While the sound is pretty innocuous as a nondescript background buzz most of the time, the base will make any hard surface vibrate. Take that into consideration before you sit in the tub with it.

The fact that it's completely waterproof is a boon, meaning you're perfectly safe leaving it in the sink of near-boiling water and using some delicate soap products.
