Go STU

Practice makes perfect, especially in the bedroom. The GO Stamina Training Unit was engineered to turn ordinary masturbation into an intensely pleasurable training session. It combines two of our most popular products into a lighter, more discreet, and more portable version of the original Stamina Training Unit.
Just like its full-size counterpart, the GO Stamina Training Unit was designed to replicate the intense sensations of intercourse, which can help users increase sexual stamina, improve performance and techniques, and heighten and intensify orgasms. The GO Stamina Training Unit delivers the same wild ride but in a more compact size, so you can train wherever you GO.

Fleshlights have MANY varieties and textures to choose from with its own unqiue feeling and that why I use them. What makes this one unqiue Is the how compact the balls are together. A little tight but it serves it purpose. I prefer the the regular STU it has more balls and theyre more compact and just has an overall better feeling. Read More

Fleshlights have MANY varieties and textures to choose from with its own unqiue feeling and that why I use them. What makes this one unqiue Is the how compact the balls are together. A little tight but it serves it purpose. I prefer the the regular STU it has more balls and theyre more compact and just has an overall better feeling.
Conclusion:
Its cool and serves its purpose. However, in my personal opinion the regular STU is the better out of the two.
This is actually my first GO fleshlight since all of mine are standard size. I had been considering a Stamina Unit for a while and since my length is within the range of the length of this toy, I decided I'd buy the GO for ease of cleaning and for a different experience. Unfortunately, while I am not quite blessed with porn star sized length, I have been blessed with porn star sized thickness at around 6" circumference. As a result, this toy was simply too tight, and I could actually feel it pushing me out, even when I would tighten the cap after putting it in. However, I realize this is not the standard experience, I'm thicker than 99% of men and just because the toy doesn't work for me doesn't mean it's necessarily bad. I did use the toy outside its case and can comment that the bumps do feel nice and have a nice intensity. However, because of it's monotexture nature, it doesn't stay super interesting and the intensity can wear off slightly for longer flights. I'm considering buying the larger size STU since I would enjoy the type of experience this offers, but for now I will keep the GO STU for any of my partners who might want to use it.
Conclusion:
I cannot guarantee the experience for those of thinner endowments, but for those with 6 or more inches in circumference, I wouldn't recommend this toy, although I do see the appeal.
I’m a bit above average size and girth and I found this fleshlight to be tight but really smooth and pleasant. Orgasms are intense with this sleeve as well and will make you want to go another round. Cleanup is pretty smooth but I will say that this sleeve requires a lot of lube, especially if you’re above average.
Conclusion:
Overall, I found the sleeve to be pleasant and will get the job done. Its smooth, gives intense orgasms and makes you want to you go back for seconds. The only downside is the amount of lube required, the lack of variety when it comes to texture and the bulkiness of the unit overall.
Introduction:
I am a big fan of the fleshlight girls product lines. I have many FLG and I love looking and useing them as well. I have a launch but the bluetooth sucks, still it does the job in the automatic mode. I recently got a sleeve warmer and it has changed the game completely. I am a big fan of edging and getting to the point where I orgasm then backing off, slowly building a mind blowing orgasm. I do like to review and rate my sleeves, I am not as intricate as some other users, just what my experience is.
Review:
I absolutely love this texture. When I am on a mission to get off and to have a long orgasm session, this is the texture I use. The key to this texture is to use plenty of lube, and vary your strokes. My technique is I start slow and shallow, then work my way up to deep still varying the speed. The orgasm I get from this texture is out of this world. Its not realistic as it can be described as very intense. As a bonus if you add a twist, it amplifies the intensity. The texture is consistent throughout so you can keep the same intensity but vary the depth and speed.
Conclusion:
One of the best textures I have that fulfills my mission of having as many orgasms as I can in my sessions.
I have this sleeve with the butt orifice and it's one of my all time favorites. The STU texture is wonderful--just like the original. However, the (smaller) "Go" size is a huge plus and so is the tighter canal with thicker walls. That is what sets this sleeve above all the rest.
Size:
The bulky size of the original makes it hard to handle during use and harder to store discreetly when not in use. The smaller Go size is an improvement in both areas.
You can easily hold the Go sized shell and stroke it with one hand. That makes it a lot less cantankerous to use than the original. Also, it's easier to stash away somewhere discreetly and pack up in a suitcase. Big win for the Go size!
Tightness:
I have an average size penis (6.5" long, 5" circumference) and have always thought the original Fleshlight size is not tight enough. For this reason, I generally use my original sized Fleshlights without the case (squeezing with my hand for extra tightness) or with sponge strips stuffed into the enormous plastic case. With the Go STU sleeve, I can use it without these accommodations which makes setup easier and faster. Everyone has their personal preference, but I think the Go STU is very pleasurably tight. Definitely the best FL sleeve I've tried in this regard.
Texture:
I really enjoy STU texture in both its original and Go sizes. The lack of variation throughout the canal doesn't bother me at all. It feels great throughout.
Conclusion:
This is one of my all time favorite. The STU texture is wonderful and the smaller/tighter size is a huge plus. This reduced size is plenty big for my average sized penis. I don't think you'll have problems with this sleeve unless you are in the 99th percentile for penis size. I really wish the company would make more sleeves in this size including some FL girl inspired ones.
I'm average length at around 6 inches and average girth. I also own the regular STU as well as the Flight Pilot and the Stellar.
The only way to get into this is with a LOT of lube. And even then, it's so tight that it's almost unusable. The stimulation on the head I intense that I don't really notice much feeling anywhere else. This is a far cry from the original STU, which is pretty much perfect. I think variation and realism are way overrated. There is no variation to this.
Conclusion:
This might work for smaller penises. I'm average and this is way too tight. I only use this when my other ones are drying or need cleaning. Almost unusable. The regular STU is phenomenal. This is dismal.
