The Jack sleeve is designed for males. It is full of texture and is well made. This toy can be used by any male, beginner to more advanced. This toy is considered a masturbator and is used in stimulating the penis. The Jack can be used by yourself or if that special lady is willing to give you hand, it can be used with a partner. My husband and I had two different outlooks on the product. Of course I could not physically use the toy myself but found what I saw to be something I would imagine would be rather stimulating and enjoyable. He on the other hand found the product to be just the opposite. He said it was uncomfortable and rough. It did not stimulate him like most other toys.

The Jack is made of TPR (aka) TPE. TPR is a rubber polymer blend that has a thermoplastic character. This allows the product to be flexible and withstand high impact strength. TPR is also somewhat porous so if sharing this product with someone else it is recommended that a condom be used. It rates in at a 7 on the safety scale and has some safety features such as, it is Hypo Allergenic, latex free, and Phalates free. When opening the box there was no smell. Even when I smelled the product there was no smell which is a plus because I hate getting toys that have a nasty smell to them. When I first touched the toy I was a amazed at how soft and squishy it was. I was not expecting it to be as flimsy as it was. I don't mean flimsy as in not made well because both my husband and I agree that it is a very well made toy especially because it is made out of the TPR. The toy itself is really stretchy. The opening where the penis is placed however is not as stretchy as we were expecting. My husband is not huge but for what he is he had trouble getting into the toy. It took a ton of lube. The outside of the product is smooth but has a very stick feel to it. It was sticking to my papers and is a complete lint magnet. The interior has a ton of different textures. It has nubs, ribs, swirls, and beads. My husband did not like the interior he found it to be to rough and quick frankly unpleasant. When I stuck my finger in the hole I was amazed at his dislike. I could not understand why he was not impressed with the texture.

The best way to describe the overall shape of this product would be a snowman or a small caterpillar. It has three balls each with a different interior texture. In between each ball there is a swirling texture. The opening of this product looks like a mouth and has some small nubs about 1/2inch in. The first ball contains a beaded and swirled texture. The second a ribbed texture. The third has a ton of little nubs. They look like tiny little rounded spikes that are very soft, flexible and squishy.

This product has a lot of "sucking" power behind it. When I stuck my finger in the toy it got really tight around my finger almost like a chinese finger trap. My husband enjoyed the sucking feature of this toy but said that a lot of the textures where to rough for his liking. He actually got a little raw from using the product nothing horrible but he was sore after using it. I would not recommend this product to those well endowed. He also did not like how tight it got when on his penis. The Jack unlike most masturbators or sleeves does not have a hole at the other end. This makes proper cleaning somewhat difficult.

The main function of the Jack is to stimulate the penis. While it has a lot of texture and sucking power I think it would be a great toy for this job. My husband did not find this to be the case. He just was unhappy with the toy in general. It was not what he was expecting at all. He found some of the textures such as the ribbing to be painful and irritating. He even tried putting it in some warm water to help simulate a more realistic experience and could not find a happy medium with anything he tried. He also had to use a large amount of lube just to get into the product. It is a very easy product to use simply put some lube on the mouth part of the toy, insert the penis and stroke away. I would recommend using lube while the product is soft and squishy with all the different textures the lube helps allow for easy gliding. My husband was not able to reach ejaculation with this product. He had a hard time stay hard and being aroused with the product even when I gave him a helping hand. Another problem my husband had was getting the toy off after use. The sucking power behind this thing is amazing. My husband described using the product as follows: "It feels like I am getting a blow job by someone who is dragging their teeth." One good thing is this product does not require batteries.

Due to the fact that the Jack only has one hole in and out, it makes the cleaning rather difficult. This toy cannot be disinfected with boiling water. The best things to use are warm water, mild soap, or toy cleaner. We ended up using both when it came to cleaning. We would use the toy cleaner first spray both the inside and outside then wash it with warm water and some soap. We left it sit out to dry due to the fact that it only had one hole and it was hard to get anything in there to clean and dry it. Once dried we stored it in a cool dry place. We kept the packaging and used that as a way to store the product and keep it from collecting any dirt. Also the only lubes to use with this product are silicone and water based lubes. Other lubes can damage the material this product is made from.

The Jack comes in a clam shell like plastic packaging. The product is visible in its packaging. Once opened there is a paper insert which does not contain any useful information just the name of the product and a picture of two males. Also inside there is a piece of plastic the toy is actually sitting in. Its hard to explain I posted a picture so that you can see what I am talking about.
