The Sorority Screw is an extremely textured vibrator meant for the vagina. Although it does work very well for clitoral stimulation as well.
I also find it to be great for foreplay, solo and couple play, and is travel friendly.
It is a waterproof toy and it makes taking a shower a lot more fun. It has many ridges which make for an amazing feeling.
It has a removable sleeve so you can change it up to get a very soft, textured stimulation with the sleeve on or a hard yet smooth one with stronger vibrations with it off.

The Sorority Screw has two parts to it, the toy itself which is made of plastic and the sleeve which is made of silicone. It has a very light odor, nothing bad, and is easily removed when washed.
It is non-porous, phthalates and latex free, hypo-allergenic and is made of food-grade material.
Without the sleeve it is very smooth and straight making it very easy to slide in. The sleeve appears rigid since it looks like a screw but it is very soft. Of course, the vibrations are much stronger if you use it without the sleeve on.
The sleeve stays on pretty securely when the base of it stays dry, but once lube starts running down and getting under the sleeve it can come off very easily so you need to have a good grip at the bottom of the sleeve.

The Sorority Screw looks exactly like that, a screw. It's 6 inches in length with about 5 inches of insertable length. It's a thin one, the girth is only 1 inch with the sleeve on and about 3/4 inch without the sleeve.
The screw design does work like a screw, it was easier to insert when turning it rather than to just push it in. I personally prefer thicker toys but this one was still fun and since it's so thin without the sleeve it fits well around the clitoris.
Being that it's on the thinner side it makes for a great beginner toy with out the sleeve, the ridges are very close together and may be a little rough for someone who is new to toys but since it is removable I very much recommend it.

This is a very simple vibrator to use. It is powered by a dial control, meaning it turns left or right. The more you turn it the stronger the vibrations get. Although it's easy to turn on and off, I personally prefer button controls, if my hand slips and turns the vibrations down on me I get frustrated.
It is powered by 2 AAA batteries and it's waterproof. It's great to take in the shower but I wouldn't try to fully submerge it if taking a bath or using it in a jacuzzi.
As far as the noise level goes, it is pretty loud especially when on the highest setting. It can be heard through the noise of the shower going and having the bathroom vent turned on!

Being that it's made of silicone you can't use silicone based lube or it'll ruin the toy.
Storage is pretty simple, just wrap it in a lint free cloth, I noticed that it did attract some fuzzies.
This is such a easy toy to clean especially since the sleeve is removable and it's waterproof. You can clean it with soap and water and the ridges are far apart enough for you to clean in between them. You can boil the sleeve to disinfect it and with the sleeve removed you can wipe down the toy itself with alcohol to sterilize it.

This vibrator comes packaged in a clear, plastic that isn't very easy to open. I had to use scissors to cut it open only to find that it did have a cut out in the middle of the packaging. It doesn't have any care or maintenance instructions on it. It's very obvious what it is since it's clear so if giving it as a gift you will definitely need to wrap it up and it can't be stored in the original packaging.

This toy did great things for me. I love that the sleeve has so many ridges and is shaped like a screw which allows for different sensations than what you get from other toys. I used it in the shower and it was great since I was already having fun sudsing myself up.
What I think is my favorite part about it is the removable sleeve. It does not have a flared base on it, so it's not recommended for anal play, but since it becomes a lot skinnier without the sleeve, it was great for me during anal play. I am still getting used to anal and my husband is obviously a whole lot thicker than this toy is but it helped to get me feeling more comfortable and ready for him. I did, of course, take precautions and was careful while using it in that area.
This is a toy I'll be using a lot and I do think that many others would enjoy it as well.
