The Quivering cock is best used in the vagina. If you are adventurous you could use it anally as well. The head of the vibrator can be used on the clitoris for excellent stimulation. This toy would be good for any woman or a couple. This is a large vibrator and would only be usable in private. I must say it worked wonders at clitoral stimulation and anal stimulation. When inside of the vagina I could feel the veins and some of the vibration. Most of the vibration seems to be in the head alone.

The Quivering cock is made of Sil-a-Gel. Sil-a-Gel is anti-bacterial and latex-free. It smells of rubber, and is only noticeable if you put it right up to your nose. The Sil-a-Gel is soft to the touch and I liked the feeling of the material. The material has no taste to it and is very smooth on the underside. The veins on the vibrator are raised for added feel and adds a bit to the stimulation. The material has a tendency to collect dust and particles. A condom is recommended for anal use. The material used has been updated to by the manufacturer from rubber to Sil-a-Gel. Anyone could use this vibrator as long as they are into big, long things.

The Quivering cock looks just like the real thing. It is 10 inches in length and 5 1/2 inches in girth. The diameter is 1 3/4 inches and the insertable length is 9 inches. It has raised veins on one side and is smooth on the other. The head of the vibrator is where most of the vibration is. The head of the vibrator worked really well at clitoral stimulation. The shaft of the vibrator was a bit too hard for my liking. It was just less material on the shaft, so when you touch it you can feel the hardness of the vibrator underneath. When the vibrator is inside the vagina you can feel that hardness. I enjoyed the head of the vibrator more then I did the rest. The size of this vibrator would be for anyone that enjoys toys of the larger size. Since it is a substantially large toy, it is not something that can be left lying around in plain view.

The Quivering cock comes with a dial base. You turn it to the level of vibration that you enjoy. There are no stops in between so when you turn the dial the vibration increases. Most of the vibration is in the head of the vibrator. I enjoyed the vibration of the head, but the shaft was just a bit to hard so that I did not feel the vibration as much. With the length of the vibrator it is rather hard for a solo player to change the controls. If using for solo play, I would have to say set the speed you like beforehand. The toy was very noisy at first because of the batteries vibrating inside the vibrator. My husband took the batteries out and wrapped them in pieces of paper plate. After that the noise went away and the vibration was still the same.

When I got this product my first thought was, "I wonder if I can remove the sleeve from the vibrator so when I clean it water won't get into the vibrator." So I asked my husband and sure enough he got the sleeve off and then back on. Clean the product with mild soap and water or toy cleaners. You should clean it before use as the Silagel attracts dust. Always clean it after use. When the toy is completely dried you can store it in the package it came in. This product can be used with silicone lubricant. The package states to remove batteries when done so that the life of the vibrator will be longer.

Most of the vibration was in the head with only a small amount in the shaft. The shaft itself felt hard because you could feel the hardness of the vibrator underneath the sleeve. The clitoral and anal stimulation I got from the head was amazing. Inside the vagina is OK, but I expected more. My husband used this toy on me and he enjoyed the excitement that it gave me. If there was a way to make the sleeve and head the vibrating part without the hardness and maybe make it movable, I would be in heaven.
