Key Charms curve - g-spot vibrator by Jopen - review by Ryuson

G-spot vibrator by

Certainly didn't charm me!

While the Key Charms doesn't suck, it won't be becoming my favorite toy any time soon. It is pleasant to use for g-spot stimulation, especially if you need a little toy to travel with, but for the power, type of vibration, and loud volume the price tag seems a bit much.
Waterproof, good material, effective at light g-spot stimulation, comes with bag
Loud, weak, buzzy, a bit overpriced

extremely useful review


The Charms Curve is a small vibrator from the new Key line by Jopen. The Key line is more affordable than the Jopen Vanity line, and is also lower in quality.

One way to use the Charms Curve is externally. This is probably the way most people will prefer to use it. The pointed tip is good for pinpoint clitoral stimulation, but you can also use the back or side of the toy for broader vibrations.

You can also insert this toy vaginally. The smooth surface and thin girth make it easy to insert without much warmup, and it's very easy to thrust with. Once you have this toy inserted the pointy, small g-spot curve is nice for moderate g-spot stimulation.

Even though this looks tempting to use for prostate stimulation, DO NOT insert this little guy anally. It has no flared base or real handle to keep this from becoming a trip to the ER. If you want an anal toy, go for something with a safe, wide base.

If you want something to introduce into a relationship, this toy would be okay. It's petite and would be nice to use for foreplay, and it's a good design to use externally during intercourse, but the quality is a bit lacking for what you get and I would recommend looking at a few other options.

I feel similarly about this being your first toy in general. While it's versatile, a good material, and has several settings, I feel like you can get better toys for a similar price on Eden. If you have your heart set on this toy it would be an alright option, and I wouldn't hate to get this as my first.

This toy doesn't quite get my dorm seal of approval. If you have thick walls or turn on music this probably couldn't be heard in another room or out in the halls, but if you're using it in a quiet dorm at night you might get some skeptical people the next morning. It's a great size and material, though, and is totally waterproof.

Material / Texture

This toy is made entirely of silicone, plastic, and metal alloy. With this being a Jopen toy I assume that the metal is a stainless steel alloy, but no matter what metal these safe, high quality materials.

Silicone is rated a 10 out of 10 on the Eden Safety Scale. It's nonporous and body safe, meaning that it won't leak gross chemicals into you and that bacteria can't live under the surface of the toy. It's flexible and soft, and usually has a bit of drag to it.

Metal, especially steel, is also nonporous and body safe. Both metal and silicone can be disinfected by boiling them for several minutes.

Plastic is rated an 8 out of 10 on the Eden Safety Scale. It's very firm, and almost never has any drag to it at all. Plastic can't be boiled, so in order to disinfect the plastic portion of this toy you should wipe it down with a 10% bleach solution.

Silicone is a very soft material, and the sleeve that fits outside of the bullet of this toy is very flexible. The bullet is very firm, so when inserted into the sleeve this toy is very rigid up until the tip, which is soft.

So far Eden only offers this toy in a lavender color. This is my least favorite color offered by the Key line, but I really liked the design of this toy. The bullet is black, with a metal, silver button on the base.

The sleeve of this toy is entirely smooth. This is the only Key Charms toy that doesn't have an interesting texture, which was another reason why I chose it. The black bullet has a pretty big seam on it, but the silicone sleeve has no seams at all.

In total, this toy is made of great, safe materials. It's smooth, and the flexible sleeve makes the tip not super pointy. I don't like toys that feel like they're gouging out my g-spot, so that's a plus. I think that the soft tip would be good for newbies to toys, but that everyone will like how safe the materials are.

Design / Shape / Size

The Key Charms all have very unique designs. The others in this line all are straight shafts with different textures, but the Charms Curve is a smooth shaft with a pointed, curved tip. I chose this design because I'd rather be able to use a toy for g-spot stimulation than have a better texture, but I'm still tempted to get one of the other ones, as well.

The Key Charms Curve is 4 inches long. It's listed as having a 4 inch insertable length, but if you want to hold on to this toy and thrust with it you can only really insert about 3 inches. This toy is also 3.25 inches around at the widest point. The Charms Curve is much smaller than the average penis, so you shouldn't have any size envy issues if you use this with a partner.

The tip is about .75 inches long, and comes to a fairly sharp tip. There are several toys out there with this design that are firm, and quite a few people complain that they're too pokey. This design doesn't gorge your g-spot, but just puts a fairly firm pressure against it.

Even though the shaft is uniform, I had no trouble telling if this toy was facing the 'right way.' If you have large hands the thin girth might make this a bit hard to hold, but most women will be fine with the size.

The bullet inside of the toy is the same for all Charms toys, they just have different sleeves. This bullet is about 3.25 inches long. You can use the bullet on its own, but then you defeat the purpose of paying such a high price tag for this toy.

If leave this toy out it's fairly obvious what this toy is, especially since it's a pretty standard toy design. The small size does make it easy to hide away, and this would even be small enough to carry around if you're one of those women who likes large purses.

If you have a fairly easy to find g-spot that's 3 inches in, this toy is going to work well for you. If you're a size queen or like feeling full, or even if you like to have firm g-spot pressure, this probably won't be a good addition to your toy box.

Functions / Performance / Controls

The Key Charms Curve has just as many settings as the Io and Nyx, but they feel much less satisfying. Even though this toy has the same variety, it's much louder and is quite a bit weaker than the Nyx, and it's pretty buzzy on top of that.

The Charms Curve has five settings, all controlled by a single button on the base. When you thrust this toy it's instinctive to put your finger on the base, right on top of the button. Because of that it's pretty easy to accidentally change the setting during use. You hold down the button to turn it on, and then you press it again to cycle through the settings. The settings are as follows:

1) Solid (Low 3 vrooms, 3 bees)
2) Bzzbzzbzzbzzbzzbzz
5) bzbzBZBZ bzbzBZBZ

To turn this toy off you just hold down the button for 2 seconds. This makes it easy to turn off in a hurry. When you turn the toy back on it starts back at the first, solid setting.

While the vibrations at this toy are strongest at the tip, you can still very much feel them in the shaft of this toy. You can feel the vibrations in the base of this toy, but they aren't strong enough to numb my fingers.

If you take the bullet out of the sleeve it's a bit more powerful and quite a bit louder. If you are planning on taking the bullet out of the sleeve you should just invest $30 in a basic bullet with more power and functions, because this toy is really only this price because of the sleeve it comes in.

I have used this toy in the shower and washed it several times, and neither time did I find any water in the battery compartment. The o-ring keeps this toy waterproof, which makes it very convenient to use. The vibrations were the same strength under water.

The Charms Curve was a total dud for me. It's much louder than the other Key toys I have reviewed, and at the same time it's buzzier and weaker. While it is a bit more useful than the Key Io, I can't justify the price tag for the quality.
    • Easy to use
    • Multiple settings

Care and Maintenance

This toy is super easy to clean and care for. This toy has no seams or ridges to catch gunk, so you don't have to worry about that at all. It also isn't a lint magnet, so you can totally get away with just cleaning this toy after each use if you keep it in a clean place. I clean this toy with an antibacterial toy cleaner, but you can just as easily use soap and water or a toy wipe.

The best way to disinfect this toy is by wiping it down with a 10% bleach solution. This should be done every time you switch users to prevent the spread of bacteria and infection. You also can remove the sleeve and boil it, but the bullet should not be boiled.

Silicone should not be stored in contact with other silicone toys because the two could react together, especially if they're from different companies. Similarly, you should not use silicone based lube with silicone toys.
    • Easy to clean
    • Easy to store


The Key Charms Curve comes in fairly nice packaging. It's different than the traditional Jopen packaging, which is a white box with the image of the toy on the front, but it's not different in a bad way. If anything, the packaging of the Key line is a bit more playful and approachable.

The front of the packaging has a slogan about the toy and an image of it. It's entirely black, white, and the color Key Charms toy you got. It has some minimal information in small print about the functions and what kind of battery it takes.

The back of the packaging has an image of the toy, again, and bullet points highlighting the most important features of the toy. On the sides are instructions in several different languages.

Inside of the outer box is a black box with white text. This gives you basic information about the entire line. It also talks about the quality guarantee and such. This opens up to show the toy itself. Under the insert that holds the toy is an instruction booklet and the storage bag. The storage bag for this toy is actually large enough to hold two of this toy.

This packaging would be great to wrap up and give as a gift. It's obvious about what's inside, but at the same time it's playful and attractive. I use the storage bag for storage because the box is pretty bulky.

Here's the outer box:

Key Curve Front

The inner box:

Key Curve Closed

    • Good for storage

Personal comments

The Charms toy are part of the Key line that are listed as 'Petite massagers.' There are also two smaller toys called the Nyx and Io, which are listed as 'Mini massagers.' The Nyx and Io are similar in price and appearance, but the Charms are a bit cheaper.

The Charms toys are smaller than the Nyx and Io, and offer more variety in texture. The Nyx is entirely smooth, and the Io has a bumpy sleeve and a smooth sleeve.

The Charms Curve is much louder and weaker than both the Io and the Nyx. It's really not comparable to the two 'mini massagers,' because the $10 difference is huge when it comes to quality. Here's a photo to compare the three:
Io VS Charms VS Nyx


I got the Charms Curve, Nyx, and Io the day they came out on Eden because I was so stoked about this whole line, unfortunatley the only one that seems to be worth the price tag is the Nyx. The Key Charms is weaker than the Nyx (and actually a bit weaker than the Io) and is louder than the both of them.

I think that this toy is a bit more useful than the Io because it can be inserted. When the Io is inserted the loose sleeves move around and are awkward, but this toy can be used for some pleasant, gentle g-spot stimulation.

Even though this toy isn't awesome, I'm tempted to pick up another Charms just because the textures are fascinating. I wish that this toy had more oomph and a bit less buzz, but it is silicone, waterproof, and does offer a few functions.

I rated this toy a 3 out of 5 because it's not awesome, but it's not awful. It's a bit overpriced, and there are better options for toys in this price range, but if you want a thin toy with a soft g-spot tip this is fun to have around.
