I think this only works well for external simulation. It's a decent size but would not want to use it for insertion anywhere. It is fairly quiet; I have had louder toys. This would probably be OK to use even if you have roommates, as I do not think it can be heard behind closed doors.

This slim, smooth baby is made of mostly ABS plastic, but it does have a little silicone where the function/on/off button is. I think this is a plus because it's easy to clean, and you can use any lube you want with it without the worry of messing it up. I smelled no distinct smell upon opening. It is hard all over except where the button is, of course.

This Slender Slim 5 Function toy is surely slender and slim. It's much like a bullet but longer. It looks nice with its metallic coloring and sleek look. It's simple yet has 5 functions, which are also simple to use. The only button it has is at one end, and it is the function/on/off button. It goes to the first function when first pressed, then goes through the rest of the functions, and after the last one, just press again to turn off. It is 6-1/4 inches long and a little over 2 inches around. It's easy to hold in your hand but it wasn't the most comfortable to hold for me because of the solidness of it.

It has 5 different functions, ranging from slow to fast, and from pulsing to steady. I personally like the steady vibrations the best. I think, in a way, it's nice that all functions can be controlled by one button, but then it can be not so great in that you have to go through all of the functions to turn it off. I would say it is decent in the vibrations but I have had bullets that are more intense. It may be great for a beginner or someone who doesn't like strong vibrations.

This little toy is one of the easiest toys to clean and maintain. With it being waterproof, you can clean it without the worry of messing it up. Plus, with it being non-porous, there is no need to spend a lot of attention and time to its cleaning--just a little soap and warm water should do the trick. I personally like to use toy cleaner on my toys. I recommend the spray toy cleaner--it makes care and maintenance that much easier.
