Jack Grip is a great masturbation sleeve when you are either alone or with a partner. You can even use it with a little oral pleasure. You can have your partner sucking or licking the head of your penis, while stroking the shaft with jack. He has finger grips on one side, so your hand won't slip off with fast thrusting. You should place a few drops of water based lube, or saliva on the shaft, because it does seem to want to stick to skin just a little. Because Jack does have finger grips, he is a handheld sleeve. He stimulates the shaft and the head the penis very well. He is great for all types of men; gay, straight, single, or in a relationship, and all sized men. You can use him alone in bed, and in the shower. He seems even better with a partner, which can be anywhere.

Jack is made of Sil-A-Gel. He has a slightly fruity smell, which isn't too bad to me, but my boyfriend didn't seem to like it. Jack is very smooth to the touch on the outside, and on the inside he is ribbed, which may feel like the vaginal walls of a woman. Because of the ribbing, the inside of this sleeve may provide added stimulation for some men. It did for my boyfriend. Jack is very soft and squishy, which is great, because it allows you or your partner to apply pressure on your member as you or they like to give.

Jack Grip has a length of 3.5" and can fit up to 2.5". he is made from sil-a-gel. My boyfriend is little bigger than average, but this still worked well for us. The shape of Jack seemed a bit odd to us at first, too. One end of the sleeve is larger than the other. This was the first sleeve we've ever tried, so we were a little confused. We just picked the bigger of the two ends and went at it.

Jack's size is a little intimidating at first, because all the ones I have seen are small and very flexible. Jack can stretch a little, but not too far like some other sleeves I've seen. He's also the only one I've come across with grips for your fingers. He fits in the palm of your hand for a good grip with places for your fingers, like I have already said. When held in your hand, the size feels similar to holding a can of soda.

Jack is easy to hide and very discreet. You just have to find a spot that no one will go into, like a sock drawer. He is good for travel, as long as you have him in bag of some sort.

Jack's function is very simple to operate, and his performance is GREAT!!!! You should just put a few drops of lube around the head, slip him on and go. Jack worked really good for my boyfriend and he loved it that I was doing all the motions and pressure for him. My boyfriend loved the stimulation from the sleeve. He said it was like being in me, which is good, I think. The best part of jack is that he ribbed and you can increase the amount of pressure on the shaft and head. Because Jack is made from sil-a-gel, he is waterproof, which is great for the guys that live with roommates, or in a dorm. We have yet to try him in the shower.

Jack is easy to clean. Just use warm water and mild antibacterial soap before and after each use. You can even use your favorite toy cleaner! The manual suggests that you dust it with baby powder to lessen the stickiness, but you should actually use corn starch, which is good for your body. Don't forget to clean the inside too! It's also relatively easy. Just flip Jack inside out and repeat the same process on the inside as you did on the the outside.

Storing is relatively easy. You can leave it in the packaging it comes in, or put it in a toy box or drawer. For us, personally, it's a bit more difficult. We still live with family, so we have to hide the sleeve from everyone. Our solution was to toss the box, store Jack in the bag it came with, and place it in a sock drawer.

With sil-a-gel it says you can use water and silicone based lubes. But in the user manual, it says to use just water based lubes, so it is kind hard to know, I guess. You could test both on the fingers grip, if you really wanted to know.

The Jack Grip is packaged in a fairly small box. On the front it has the company's name and a picture of the sleeve itself, with a little motto for the toy, which reads "If you don't have a grip, you don't have Jack". On the back of the box are details about the sleeve, like what it is made from, how to clean it, etc. There was a user manual included which stated the cleaning instructions, how to store the sleeve, and how to keep it smooth. If you bought this sleeve, or are thinking of buy this sleeve as a gift, you can keep it in the box and just place the whole thing in a gift bag or wrap it. It is great for storage if you don't have room in your toy box, or you want to keep it in your sock drawer, or where ever you personally keep your toys.
