I’ve had the SI-X Type F on my wishlist for months, eager to see if the "great blow job simulator" claims posted in other reviews were true. While I wouldn’t say the SI-X gives good head, it does offer a nice masturbation experience for a fraction of the cost of some of the top of the line masturbation toys.

For being above average girth & length, this toy really impressed us in how well it stretched! It takes a lot of lube due to the ribbing on the inside, but it's worth every ounce used. It's definitely as close to the real thing as we've found in a toy, even if the material is porous! One might want to stay away from the lube, however, since nobody seems to know what's inside of it!

This sleeve is really amazing, the only con being that it's not amazing enough. I'm giving it 5 stars, but I am slightly disappointed that the middle didn't offer something outstanding too. Still, this is truly a great toy and belongs in every boys toy chest. On a side note, for the 98% who don't get it, the title is a reference to a hentai series.

This is definitely a "have to try" toy for any guy out there! Ladies, this might be a great gift that you could give your guy for Valentine's day maybe, huh? It's good quality, it's pretty easy to clean, comes with some great lubricant, and the most important, it gives you an orgasm!

It's an inexpensive, but better-than-expected blow job simulator. Honestly, it's probably worth more than what I paid. I suspect it's the look of the thing that drives the price point down, but it just goes to show: sometimes the plain Jane is the better cocksucker.

This toy should be the only blowjob simulator in your collection. The material adapts to any size and feels like the greatest BJ ever. Great lube makes this toy even better. Easy to grip and control for max pleasure. Not too big for easy storage during travel.

The Si-x type f sleeve is more than an interesting name; it is by far the best oral stimulator on the market. The interior of the sleeve was designed to perfection with even an imitation tongue with taste buds! With one of the best interior designs on the market also comes a very easy to clean sleeve that does not require a lot of maintenance. This sleeve will surely keep you coming back for more.
