This is a fantastic toy for external teasing. We like it best when he uses on me during foreplay, but men will also enjoy the teasing of the shaft and testicles that can be achieved with this. You can also tease nipples and the external area of the anus.

This is not at all suited to internal stimulation. I especially wouldn't try it anally, because a stray muscle spasm could pull it into the body.

The silicone used for this is actually surprisingly not a lint magnet. It doesn't seems to attract much of any schmutz. Anything that doe end up on it just wipes off.

The silicone is matte and smooth with the exception of the PicoBong logo embossed in the side. The plastic is shiny. I don't particularly like texture, so this was fine with me.

The silicone is flexible at the ring, but was rigid along the rest of they toy. The silicone had no odor or taste. The plastic base is completely rigid. Silicone and plastic are both non-porous.

The IPO is kind of like an elongated egg in shape. The slightly wider end is where the battery is inserted while the thinner end is for pin point stimulation. The ring portion comes off the bottom. The ring is a hit tight on my fingers. I have larger fingers for a woman, but they are pretty average for men. The ring stretches to fit, but only so far. This isn't something I would suggest for those with very large hands.

IPO is a dainty little thing. It is only about 3.25" long and about 3" in circumference. This makes it the perfect toy for tossing in a bag when going traveling.

IPO is powered by 1 AAA battery which is inserted by unscrewing the plastic portion. The battery compartment is waterproof, so feel free to take him on your aquatic adventures.

The toy is controlled by a + button located in the B of the logo and a - button located in the P of logo. In my opinion, these are terribly inconvenient for using on yourself if you are right handed. The buttons end up on the right side, so you can't push them with your thumb. Lefties will have an easier time.

The are no patterns. The + turns the IPO on and makes the vibrations stronger while the - does the opposite.

The IPO is pretty damn quiet. Maybe not discreet enough for a dorm, but plenty discreet for use behind a door.

Silicone is a 10 on the EF safety scale because it is sterilizeable, but because this has a plastic base, a lot of that is lost. You can still wipe it down with a 10% bleach solution to sterilize it, but you can't boil it. This is cleanable with mild soap or toy cleaner and warm water. I would highly recommend removing the battery before cleaning.

Make sure to pay attention to the embossed logo during cleaning because fluids can be trapped there.

Silicone cannot be used with silicone lubricants, so make sure you stick to water based lubes. Same rules apply for storage. You don't want to store this touching other silicone products.
