Cinder

Full disclosure, I haven't put a lot of use into these bullets. However from my experience, they do well as an "extra hand" when enjoying foreplay with my partner. Typically I will either use one on my partner's clitoris (with a strip of masking tape) or on other erotic points that she enjoys vibration. This lets us enjoy kissing or begging without my hands or mouth needing to be working at all times. For that kind of light use, these little guys are great!

However I should point out that their plastic, and the wire connecting the controller to the bullet both feel very cheap, and I wouldn't be shocked if an accidental pull would break the wire or just kill the device entirely. (I haven't had this happen, but I've been quite delicate with them.)

For 9 dollars, this toy does it's job, and I'm satisfied with my purchase.

Not much to say that hasn't already been said, but this is a very good, high quantity, lube that works well for onaholes and other sex toys.
my only problem with it, is that it dries too quickly when exposed to air. I rarely masturbate with my hand, but this lube needs constant reapplication when I do. For other uses it does just fine.

I originally bought the RDT after reading some reviews that it feels a lot like a realistic mouth to throat experience. One reviewer even saying it felt a bit like forcing yourself into someone's throat. Needless to say I had to try it, and I was really not impressed.
The big problem here is that while the RDT does have the right structure of mouth to throat, it is not tight or soft enough to really feel like a real mouth or throat. The tightness really needs to feel like a tight band of resistance at the throat entrance and onward, while the actual hole needs to feel soft and smooth like a mouth texture. RDT strattles the line and doesn't do either very well, as it's too hard and rubbery to feel like a mouth, and too soft and open inside to give the appropriate inward pressure.

For those looking, a better alternative for the experience described above: try a mouth of truth with a wide rubberband around the mid section. It's not perfect, but it is a lot closer than this.

Had that been it, I probably would have left it at 3 stars, but unfortunately I do have to mention that due to the shape of the hole, it is very easy to accidentally leave water or soap in the back section after cleaning which (if you've ever had a wet onahole sit around for a few days) you know is not something that is fun to use.

Hi! Before I start, this review is from the perspective of a male (fairly desensitized) user, so your experience may differ depending on your equipment.

I had originally bought the Fairy wand for light teasing, and vibrating ona-hole play, however I found it to be much better as a stand alone vibrator that gets me all the way to where I need to go, without as much cleanup as a regular session (as no lube is required when using this toy).

This unit is powered by a cable to the wall, this is fantastic for never having to worry about batteries or low power vibrations. The build quality is a lot sturdier than I had expected, and I have it say it's very comfortable to use for both sex, and as an actual massage wand. The vibration wheel is extremely easy to use and control even while you're using it.

The only thing I genuinely don't like is the inset squared rings around the head of the device, as they tend to accumulate grime and need to be cleaned every few uses at least with a small brush. I would have preferred a smooth design, or a curved inset as opposed to the square one.

Also, if the manufacturers happen to read this (doubtful, but worth a shot) selling head attachments designed to work with ona-holes, or are targeted towards use with a penis would be very appreciated, as it stands most of the attachments I've seen are more focused to the female users. Luckily I do some silicon casting for cosplay so I'll probably try making some of my own designs, but I'd rather just pay the manufacturer for something like this.

The Monster Kakusei Crystal Hard, is a very good onahole for those who need strong stimulation, ease of cleaning, and durability.

As of receiving my MKCH I've given it a few dozen uses and can confirm that it has yet to show any signs of wear at all. Even the unusually small entrance (it's about q-tip sized) has yet to split, whatsoever. Because of this, the MKCH has replaced my Virgin loop crystal hard as my daily driver due to it's equally robust construction, as well as it's heavier stimulation.
Onto the stimulation, the MKCH significantly bumpy in it's interior, and while I wouldn't call the texture as exciting as other holes, I would say they do the job. However, my one major gripe is that this hole is relatively thin making the resistance of the bumps significantly less enjoyable. Because the hard material doesn't give as easily as some softer onaholes, the thin walls aren't strong enough to support the interior design. The ona seems to bend around me rather than making me push through it. I feel like if I were to cast more hard silicone at maybe 2-3 inches in diameter around the entire shaft of the hole, the extra support would make the experience significantly more enjoyable (so much so that I'm surprised there isn't already someone selling this at the 40 or $50 price point.)
Cleaning is very straightforward with this hole, antibacterial soap, warm running water, pump until water returns clear and free of bubbles, then dry. Like most hard versions I haven't flipped it inside out, and I don't think you should either, it's just not elastic enough to trust.
