The Realdoe Feeldoe also comes with a bullet vibrator. The hole to insert this bullet vibrator is at the base of the shaft underneath the giver's insertable portion. The hole is intended to fit any average-sized bullet, so it will fit any other bullet that you prefer. The bullet vibrator itself is a small, plastic bullet that uses watch batteries for power (included). The bullet is about two and 1/4 inches in length. The bullet vibrator is a one-speed bullet, and it is controlled by the push-button control on the end of the bullet. Before inserting the bullet into the Realdoe, it is recommended that you place a small dab of lubricant inside the hole to aid in removal of the bullet when you are done using it.
The single-speed of the vibrations is on the milder side. It can be used on its own as a vibrator, and it can also be easily inserted into the base of the Realdoe. When inserted into the Realdoe, the majority of the vibrations are focused along the ridging on the top-side of the shaft near the giver. The giver receives most of the vibrational strength. The vibrations can be felt very, very slightly towards the tip of the dildo, but they are not very strong in the shaft of the Realdoe. The vibrations seem like they were intended mostly for the pleasure of the giver.
Many users of the Realdoe may find that it is a bit heavy for comfortable, regular use with just the PC muscles. As the Realdoe weighs about a pound, it is heavier than almost all vaginal exercisers - and then you have to consider that the shaft will be hanging out, so gravity will work against you as well. Some women may find that their PC muscles are not strong enough to comfortably enjoy and use the Realdoe for an entire session. However, the neat thing about the Realdoe is that it can be used with a strap-on harness as well. While you might think that it would defeat the purpose of using a strap-less strap-on, it actually works well as then both the wearer and the receiver can receive pleasure from the dildo while not having to worry about trying to keep the Realdoe in. Plus, when using the harness, the Realdoe tends to stay straighter and not droop as much.
During use, the head of the Realdoe provides the most sensation. The veins of the dildo do provide a bit of a softer texture, but the head of the dildo provides the most sensation. The length will be long enough for most people to enjoy the penetration, and the diameter is great for vaginal use as well as experience anal users. The ridging along the top of the shaft near the giver does provide a bit of sensation for the giver, and depending upon the angle during use, it can be more or less pleasurable.
