In terms of sleeve, I am quite happy with the original one. Using a rigid mount for the handy and sitting on a chair I dont really have the problem of it coming loose / not staying in place, I am also roughly 15cm/6". I do it like in the manual, insert penis in sleeve, then insert both in strap and barely tighten.
Maybe you could also be interested in this: Anyone interested in aftermarket handmade silicone sleeves for the handy?
In terms of rough textures, I am using HandyControl and have set the A button to very low speed. Once I have come and get sensitive, I simply press the A Button, the handy immediately switches to slow mode regardless of script loaded and slowly massages until I am finished.
Maybe this helps.

Sounds interesting as I love the original. Would you say it is as tight? Cause I think that could be a bit much for me using the handy.
@JuAnUs Thanks, I’ll look into it. Which Player do you use? With the scriptplayer, the A button also stopped the video for me which is kinda inconvenient 
@chetbrinko Might try the milking hole, how tight is it?
@Cloudyfire How tight and intense is the Maria Nagai compared to the Bocca Verita?
Hi, HandyControl is all in one: It plays the video, the script and also allows to control the Handy with a XBox Controller.

Hey there!
I’d say it’s about as tight as the original, but overall a bit more comfortable/less strenuous because of the soft teeth and the thicker flesh material.
Unfortunately… because of the Perorin’s thickness, the Handy’s grip band barely reaches all the way round (even less so with some surface protection for the TPE in between, e.g. a sock strapped over the onahole), which means the grip band will slightly compress the Perorin so it becomes way more tight than it should be, probably even more tight than what you experienced with the regular Bocca. ;(
Nonetheless, having owned both of them consecutively, I personally would always recommend the Perorin over the original, because i think it’s a much more refined product, the sensation feels a bit more nuanced imo and most importantly it seems a lot more durable (definitely a big issue of the original - at some point tears in material are highly likely).
@zala77 the milking hole is tight but also it’s very… soft - it starts out like your dick is in pudding lol. Only after it’s been going do you start to feel the crazy suction. And then it sucks your dick off haha
Having recently received each of the three open ended sleeves I thought I should post my experience with them.
https://www.thehandy.com/product/extra-truegrip-open-ended-sleeve-for-the-handy/
These 3 sleeves available in three types, hard, soft, and medium. Each has it’s own texture.
The hard one is also the one with the most texture, a diamond grid of raised lines and small closely spaced nubs. The pattern changes half way through the sleeve and each end is very different. It provided quite a bit of intensity so I had to loosen the strap a bit. More about this later.
The medium one is quite nice and has nubs arranged in a diamond pattern throughout. This was also quite a good sensation. I did not feel a need to loosen the strap.
The soft one has concentric ribs for the length of the inside. It was the best, most subtle feeling. I could use that sleeve for hours. This was soft enough that the strap can be fairly tight with good lube, but the ribs are also soft so looser is better for me.
These 3 sleeves are just as they are pictured with no area defined for the strap.
I had trouble with each of them staying put during faster and parts of the action and the strap adjusted a little loose.
I finally tried something I read somewhere. I took an old athletic tube sock and cut about 5 inches off the toe area and put it over the sleeve. I also placed the hook side of the strap inward to catch on the sock’s material. I had to put the covered sleeve into the strap before I closed it. I only had one sleeve slip out of place after that which was during a max speed script and my lube was also running out at the time making the sleeve slide a bit hard.
To allow me to lube without stopping I cut a hole in the toe of the sock and dripped lube into the open end as needed. That was very Handy!
For the price I am glad to have all three! My favorite is the hard one - after I got it to stay put! But the other 2 can provide the same result with just a bit more time!
This is my experience and as they say, “Your mileage may vary, it depends on the speed you drive!”
Great review @hosenguy - I’d agree with most of your sentiments! 
The soft one is for sure the most comfortable of the bunch and imo also has the best sensation - I’d say even better than the original Handy sleeve. The quality level of the material on these new sleeves is definitely a bit higher.
The sleeves are indeed more prone to slip around in the strap. - I also feel like I need to leave the Strap rather loose or these sleeves will get too tight, which might have been designed better. The hard one definitely becomes a bit too tight/uncomfortable fast. But I wouldn’t say it is a deal breaker, especially if you find a workaround, like hosenguy suggests.
I would also add that being open ended means you will of course need to have a tissue ready while enjoying the Handy, which did require some getting used to, at least for me. 
Bottom Line: The soft version open ended sleeve I would recommend to any Handy owner. Feels great! …Especially if you’re curious to try out something that’s a bit different from what you’re used to.
…Though I would also admit, I do like having all the 3x strength versions as they definitely offer very diverse options to experiment with different sensations, once in a while!
Cheers! 
After playing around with the handy some more, I agree that the original sleeve isn’t too bad. it’s still too short for my taste and tends to not really stay in place that well, but it works.
I gotta say the Fleshlight Quickshot (with only one ring in) works way better for me though. It stays in place pretty well, feels great despite the lack of suction and I have a lot more control over the stimulation. If I get too close, reducing the stroke length a bit so that the head won’t get as much stimulation works fantastic and makes edging very pleasant without resorting to extreme stop-and-go tactics. I can control the session length so much better with the Quickshot!
Downsides are obviously the spill which can be quite big especially with the intense orgasms I can achieve using this and that it eats quite a bit of lube. If the lube isn’t too thick, it’s okay though. Still, the overall experience is way better for me as the squishiness even helps with the handy feeling very robotic usually.
Do you think it would be possible to trim off excess material and get it down to a significantly lighter weight? 600+ grams is a little bit more than I’m comfortable with.
Does anyone have experience with any of these onaholes with the Handy?
Ginguchi Dirty Sister
It’s 370 grams vs the 420 grams of the Bocca Della Verita (soft edition) and 430 grams Perorin soft.
Fellappuccino
420 grams and under $20.
Eternal Fella Innocent Sweet Bite
305 grams and under $20.
How u order this?
I am looking for a softer and more rigid sleeve. Tenga 3D Zen caught my eye. Have anyone used Tenga 3D Zen?
I had one very similar to the Fellappuccino, didn’t work that well with the handy. The bottom lip would rub and get caught up on the handy, plus it wouldn’t get a very smooth stroke.
Got the 3d spiral, it’s extremely intense especially with scripts like asian fuckfest. Did jump out a couple of times which is frustrating.
That’s sorry to hear. Not good. Thanks for the feedback!
Whilst reading about Tenga 3D, I came across newly released Tenga Aero. You adjust the suction to get more intense feeling. Weighs around 350 - 420g. I might buy Aero instead
Aero is reviewing well, but it’s unknown when it’s coming to the USA. (It’s on the European, Malaysian and Japanese stores right now.) The prices on the Tenga JP store place it around the same price as the Geo: ~$40.
Aero is twice that price where I live! I I am a little bit concerned about the shape because it looks like it would strap won’t be able to hold Aero properly. But I think I’ll buy one anyway because it sounds much better, more sturdier and lighter than Tenga Flip Zero. I’ll report back
I’m sad. I bought the Bocca Della Verita but I can’t feel anything (apart from the teeth). I have the impressions that I’m humping foam, there’s like no pressure at all. I’m just a teensy bit over average so I would be surprised that it was a size issue. I don’t know if I’m doing something wrong or it’s just because I’m not used to them but, in my case, I really didn’t like it. I just wanted to tell my experience to warn others that maybe they wouldn’t like it either.
On another note, I also bought the Linx Glacier Dual End Stroker on amazon and it’s amazing. I can’t use it with the handy sadly (too tight so the handy force too much during the downward stroke) but this is by far the most intense stroker I ever used. Also, you can use it in both direction and each of them are really different . Quick note, I thought it was impossible at first to enter from the smaller side but by applying enough pressure you can (unless you have a monster dong probably).
OK, it’s not just me. I also got a La Bocca Della Verita (soft) and was very disappointed. Strapped it into the Handy and meh. The stock sleeve that comes with the Handy is still the best IMHO.
Yep I agree. I tried some other sleeves but I didn’t find anything better yet that was working properly with the handy.
I also started using it sleeve without lube (it probably only work if you are not circumcised tho). Once you get the hang of how to set it up, damn that’s intense! It really feels like getting a handjob. I alternate between the two.
