Senso Lips is a great handheld masturbator sleeve, even for beginning toy users. The shorter length of the "tunnel" makes it an awesome couple's toy, particularly for men with longer shafts. It works very well when combined with oral stimulation. For example, if you have a sensitive gag reflex, this makes it easier for him to get the stimulation he wants while keeping you comfortable and able to really focus on his sensitive head! Having used other sleeves, I can say that Senso Lips is quieter and doesn't make as much of that squishy sucking sound you often hear with sleeves. I would recommend it even to those living in dormitories or apartment buildings with thin walls.

The jelly material is pleasantly squishy. The inside of the sleeve is ribbed, and feels pleasant to the touch. The outside is a bit sticky which might be unpleasant to some users, but this can be remedied with a light dusting of cornstarch. Because of the give of the jelly, this toy is great for beginners - with proper lubrication, it's very easy to use. There is a light jelly odor which may be unpleasant to some users.

The nose and mouth shape does make my partner and me giggle a bit, but once you get past that, it's such a fun toy that you'll reach for it again! The design is great because you can either pinch the end to contain semen or leave it open if you want to perform oral sex. If you have a particularly long partner, Senso Lips can even be used during intercourse because it is both open ended and relatively shorter shafted. Because the entire toy is jelly, it's very comfortable to grip in several positions. If your partner is girthy, over 5.5", he may find the toy too tight, or you may notice internal rips in the jelly. Overall, the shape and size make it a very versatile toy!

As a simple jelly sleeve, I wouldn't say that this toy has too many "functions", but it also lends itself well to quieter situations. It makes little noise, even the sucking noises associated with sleeves. Because of the stickiness of the inside combined with the tight fit, it performs the function of a masturbator very well. At times, my partner found it overstimulating, but it was very easy to adjust simply by repositioning the toy or removing it for a period.

Senso Lips is easier to clean than non-open ended masturbators, but some might find the tunnel difficult. I recommend investing in a good toy cleaner that's safe to use with jelly toys. If you or your partner are ejaculating into it, it may be more difficult to clean, but so far I have not faced this hurdle. There are some lubricants which are safe to use, including water based (which may wear off too quickly for some users). Creamy lubricants are particularly well suited for sleeve use. I have yet to find a completely suitable way of storing Senso Lips, but I plan to look at more of the toy storage options here on Eden Fantasys.

The packaging was relatively discreet, but is not suitable for long term storage. I neglected to look at it for instructions because I was fairly confident in my ability to use the toy properly.

I'm a big fan of open ended sleeves for couple's use! Unfortunately, my partner fell asleep immediately after uttering, "Holy crap," so he was unable to be reached for further comment.
