The dilator set comes equipped with a wand with a built in attachment, three different sized attachments for gradual muscle strengthening, and a ribbed silicone sleeve that can be placed on the three removable attachments. The wand itself has a vibration function controlled by a dial at the base as I stated before. There are three different levels of vibration available by turning the dial slowly. The noise factor of the dilator set varies from attachment to attachment. The attachments easily slide and lock into the base above the handle of the wand. They are made to stack on top of one another as you gradually move from a smaller attachment to a larger one. If you fail to remove the smaller attachments and instead just place the larger attachment over the one built into the wand, the noise is extremely loud and not discreet by any means or stretch of the imagination. I suggest making sure to stack the attachments as you progress rather than removing a smaller one and just placing the larger one on the wand.
Now, let's talk a few measurements. These are rough estimates, so please don't be too critical. I measured to the best of my ability. I also gave the different attachments different bee ratings, though the overall factor is a 5/5.
The portion of the dilator that is attached to the wand measures at a length of about 4" and a circumference of 2.75". It is slim and easy to slide into the vagina. This is the best way to begin using the dilator as opposed to jumping right in and using the larger attachments. The vibrations can be felt the hardest and heard the most in this portion of the wand.
The smallest removable attachment measures at about 5" in length and roughly 3.25" in circumference. This attachment is a bit larger than the stationary portion of wand, but is still easily inserted into the vagina and is comfortable for use. If you have not had intercourse for a while or are working to stretch your muscles, I would suggest using this attachment as well as the stationary portion to work your muscles before moving onto the two bigger attachments. The vibrations are not as loud, due to being stacked on top of the stationary portion, though they are just as strong with this attachment.
The medium removable attachment measures at about 6" in length and roughly 3.75" in circumference. This attachment is longer and has more girth, so I would suggest being sure you are ready to move on to using this next attachment before you use it. If you feel discomfort or pain while using this attachment, switch back to the smaller attachments for a bit longer. This attachment will stretch you more, but you do not want to be completely uncomfortable while using the dilator. The vibrations while using this portion of the dilator, stacked on top of the smallest removable attachment, are not as loud and are a bit more centralized in the head of the attachment rather than the shaft.
The large removable attachment measures at about 7" in length and roughly 4.75" in circumference. This is the longest and girthiest attachment for the dilator. I found it difficult to insert myself due to the fact that I am not highly sexually active. Even with the addition of lubricant I found it highly uncomfortable to squeeze in and my muscles rebelled in a way. If you are not completely comfortable maneuvering the medium attachment or fitting it inside, I would not recommend moving on to this attachment. The vibrations in this portion of the dilator are centralized almost completely in the head and is the quietest due to being stacked on top of the three previous portions.
The silicone attachment is a bit of a pain to work with. It can be slipped on to any of the three removable attachments, though I find it to be useless and cause more pain than necessary. Also, it is hard to get on to the attachments as well as remove. You need to proceed with caution as well with placing the sleeve onto the attachments if they are coated with lubricant that is not water based. The sleeve can only be used with water based lubricant and any other kind can ruin the material. Again, I used the dilator without the sleeve and found it to be quite a bother instead of an enhancement.
For beginners and those who have not had intercourse for a while as well as those who experience pain and discomfort during intercourse, I would recommend sticking with the first two smallest attachments for the dilator set. I would work with those portions for a while, quite possibly a month, before moving on to the medium sized attachment and working more with all three attachments before graduating to the largest one. For advanced users, I would suggest this set if you want to work the vaginal muscles more or prepare your partner to be inserted with a rather large toy that he/she is not entirely loosened up or prepared for.
This toy is definitely not easy to hide and takes up quite a bit of space. It is not discreet by any stretch of the imagination, so store with caution if you are traveling, moving, or just placing in the home.
