See my review for the Pocket Tenga Click Ball for a general overview.
In comparison, I could feel a distinct difference in textures, both very pleasant to me. This one seems a little less stimulating than the click ball, making it better suited for longer sessions. Still a winner in my book, I will be keeping a few of these on hand for travel purposes.

Tenga is in the business of getting men off and they know their business well.
I bought this and the sparks version for my frequent trips out of town, and they do what they are supposed to do quite well.
I was actually surprised how well I could feel the textures, given how thin and stretchy they are.
The thin material is quite resilient and has the advantage that I can use my hand to focus the pressure and pleasure on just the right spots.
Of course it doesn't hold a candle to full size toy but it's oh so much better than just the hand.
Perfect travel companion.

Don't let the small size fool you, Ona Pit delivers!

Ona Pit does exactly what it's supposed to do, and does it well. This is not a full size onahole. To me, it's more like a "hand enhancer".

If you are looking for the same experience you would get from a full size one or two hand onahole you would be disappointed. But if you are looking for something discreet, easily transported and easily cleaned this will deliver.
Soft enough to stretch to fit just about any size (I'm above average and Ona Pit has no difficulties accommodating me completely) and yet the textures (ridges and balls) are delightfully noticeable.
Cleanup is as easy as it gets. Flip inside out, wash with the cleaner of your choice, dry.

Way ahead of the Tenga egg or pocket products in my opinion.

Ok I just gotta say this right up front. I love the teeth!
I am so glad I ordered this oral sleeve. Everything about it just works for me. It looks sexy, the material feels nice, it seems well made and the sensation is amazing. The dual layer construction and the texture make this a nice sleeve, but what really takes it to the top of my list are he tongue and the teeth. The tongue is soft and wiggly and it stimulates just the bottom of my member in a way that feels almost like the real thing. The teeth are, well, teethy. And I absolutely love them. The sensation of just a little scraping is beautiful. Based on many other reviews, I was a little bit worried that they would be too much,, but even though I am above average in size, all they add is just a little scraping sensation, just like it sometimes happens "in real life", and I enjoy that very much. No tearing, cutting or chopping sensation at all.
My only concern with this sleeve is that the tunnel towards the end seems to come pretty close to the top of the sleeve and it bulges out pretty thin whenever i go all the way in for that nice tight deepthroat feeling. But so far that has not created an issue.
Overall, I am very happy and will be using this sleeve often.
Oh, and did I mention, I LOVE THE TEETH!

The Kupa Rina is my first dual layer sleeve and i really enjoy her. Shipping was super fast.
She is a little smaller than i had thought, but she stretches perfectly to fit my above average length and girth tool without any signs of tearing.
The visual appearance is awesome,the double lips look and feel beautiful hugging me. The dual layer has so far not shown any signs of separation. The tunnel design is good, feels nice and I can feel the detail. But the cervix structure at the end, WOW! thats a real winner. Great suction and i can use the choke point to stimulate the sensitive area just under my head like nothing else i ever felt.
All in all a great purchase, and amazing value!
