Wage War with your Battery Cage

The Ceres Original could not be more simple: it is a traditional vibrator, tried and true in style and shape. If you're looking for an affordable Jopen product that is on the simple side, this could work for you. Be warned that more sensitive users might find this one-noter too strong, and the battery cage may wage war with you!
Great colors, silicone, strong, waterproof.
Battery removal can be a pain, plastic tube, only one set intensity, not one set loudness.
Rating by reviewer:
extremely useful review


Ceres is one of the newest toys Jopen has released from its Key line. Named after a dwarf planet in our solar system, Ceres is a traditionally shaped vibrator. The Ceres Original is one of the three styles of Ceres. The Ceres lace has a lace texture, the G-spot has a curve to aid in G-spot stimulation, and the Original has a straight shaft with only a little bit of texture. The Ceres Original can be used vaginally, angled for G-spotting, or used externally as a teaser. It could also be used to stimulate the P-spot externally. Ceres could technically be inserted anally, but it is not designed for anal play. It lacks a flared base, and the slight textures on it can retain debris and bacteria. There are better toys for anal play.

Ceres can work for those who have had a toy or two and want to own a toy by Jopen. It can also work for anyone who is looking for a simple vibrator and don't need bells or whistles. More advanced users will be left wanting for more. More advanced users might wish to try Jopen's Comet (which is a curved dildo), Ceres G-spot, or Vela (which is a larger vibrator).

Ceres is waterproof, making it a great option for those who live with others or are in a dorm situation. It is also fairly discreet if it is inserted and the plastic tube in the battery cage is left in.

Material / Texture

Ceres is made from luxurious silicone. The silicone is buttery soft and as luxurious as some LELO silicones. It is hypoallergenic and non porous, which makes the toy easy to clean and gives it a longer shelf life. There is some texture on the Ceres Original. The product page is a bit bright, but if you look at Ceres you'll see a line that runs along either side of the shaft in a sweeping curve that meets in the middle. There is a seam the runs along the perimeter of the toy, perpendicular to the textures. The seam cannot be felt and has been smoothed, albeit unevenly. Some parts of the seam are more apparent than others. Still, the textures of Ceres may be felt, but it is not extreme in any way. It is manageable for beginners.

Ceres is fairly solid, but you can bend it slightly at the head, perhaps 15 degrees. It will also compress slightly if you press on the tip of the toy. It is still sturdy enough for most to angle it for G-spot stimulation. The silicone does have some plush to it when you squeeze it as well. The base of Ceres is made from plastic. The plastic is in a rich, bright color that matches your toy. The button at the base is made from stainless alloy.

There is no overt odor to Ceres.

Design / Shape / Size

Ceres is an elegant traditional vibrator. It's about average size in all dimensions, but it could intimidate those who are used to more petite toys. The average girth for a toy is around 4.5 inches, and Ceres is only slightly larger by a quarter of an inch.

Compared to Vela

In terms of discretion, it's obvious Ceres is a vibrator. If placed in its black pouch it should not draw attention, even if it's left on top of the nightstand. Still, it's best to store it in a drawer or a box under the bed. Regarding sound, Ceres can be discreet a long as you keep the plastic tube inside of it. The plastic tube keeps the batteries from jumbling and hitting the plastic inside the toy. If the plastic is out, Ceres is easily a high 3 Bees if out in air. If you keep the plastic tube inside or use a make-shift insulator, then Ceres is about 2 Bees in open air. For maximum discretion, it's best to insert Ceres first before turning on the toy. If inserted and the battery cage is insulated, then Ceres can be 1 Bee.

If traveling, it may be best to travel with the batteries out of Ceres. While unlikely, it's possible for the button at the base to be turned on if the toy is jostled during travel. Overall, once in its pouch, Ceres is easy to travel with and can fit in a medium sized purse or larger.

Functions / Performance / Controls

Ceres is easy to control with one alloy button at the base. Press it to turn the toy on its first mode. Ceres has 7 vibration modes in total. While it has patterns, the toy (as well as Vela) has one qualm: it only has one set intensity. The intensity can range based on the pattern, but Ceres can reach about 4 Vrooms. This means more sensitive users might not be able to enjoy Ceres without being overstimulated. If a solid 3 Vrooms or higher is too much, then look away from both Ceres toys and Vela. The patterns are as follows:

1. Standard Vibration
2. Rumbles
3. Wave: continuous pulses that rev up and down
4. Pulses
5. Throb: 2 big pulses and then 3 smaller ones, repeat
6. Flutter: Pulses, but every pulse, well, flutters
7. Tease: one long pulse, pause, followed by a short one, repeat

To turn Ceres off, just hold the button down for a couple of seconds. Ceres does not have a memory, so it will always start on the first pattern. The vibrations are rumbly and located at the head of the toy. Ceres is waterproof; it has an O-ring protecting the battery cage from water.

Battery Installation Information
This is a major downside of Ceres. It originally comes with a plastic tube in the battery cage. It is intended to keep the batteries from jumbling inside the toy. There's a catch: the plastic cage keeps the toy from sounding like a plane taking off, but the plastic makes the batteries very, very snug inside the toy. It can be difficult to remove the batteries from the toy.

If you desire to keep the plastic tube, then one way to remove the batteries is as follows: stand near a couch or over a bed. Hold the head of Ceres firmly in your hand. Then, make a throwing motion downward toward the bed or cushions. If you're lucky, the batteries will pop out. The plastic tubing may as well. If this is too stressful or you lose the tubing, it's not over, and you're not doomed to a loud toy. Using paper can insulate sound well enough. Just cut a piece of paper that will fit around the batteries and cover them. The batteries will not rattle, and you can remove them when the time comes. Still, the experience of a toy should not be solely based on an inexpensive plastic tube. This is probably the major flaw of Ceres. It could be annoying enough that some would search for other toys.

Battery power seems to last about 1.5 to 2 hours on 2 AAA batteries.

Care and Maintenance

Care for Ceres is simple. You can use toy cleaner, soap and water, or toy wipes. So long as the cap is screwed on tight, you don't have to worry about water getting into the toy. Be sure to pay attention to the grooves on the shaft, since debris can collect there. Even though it is silicone, Ceres does not seem to collect much lint. It may be the color, but Ceres only seems to collect a stray hair if that. To prevent anything from getting on the toy, just place Ceres in its pouch once clean and dry. You can store Ceres in the box it came in, but the pouch is easier overall.

Only use water based lubricant with Ceres.

    • Easy to store


Packaging for Ceres is uniform to the Jopen Key Line. It comes in a box that has a card stock sleeve over it. The design is done in the color of the toy. The sleeve has the toy on the front, so the packaging is not discreet in this way. Remove the sleeve and you'll see a black box. The black box has a door that opens to reveal the toy. There are no further barriers between you and the toy. This means that the toy can fall out of the box if you turned it upside down. Just be careful not to drop your toy to the floor thinking there is further molding to keep it contained.

Also, while some other Key toys have the pouch and instructions for the series in front of the toy inside the door, Ceres has the instructions and pouch located behind the toy. Just remove the toy or pop out the black Styrofoam to release them.

The instructions are present on the box and in the insert. They are thorough, describing how to install batteries and the do's and don'ts of the toy. Ceres could make a wonderful gift depending on the user. The pouch or box can be used for long term storage depending on your storage space.
    • Very informative
    • Good for storage


Now, I've given Ceres 4 stars, but it's more like a 3.6. Here's why:

1. Noise Levels Alternate: This toy does not have one set level of noise. If it's out in air, inserted, held by the base, or held somewhere else, the amount of noise changes. This is not very reliable. Also, if a toy is the price of Ceres, I do not expect a major part of functionality of the toy to be dependent on a cheap, plastic tube. Why buy the vibe in the first place? The plastic tubing makes battery removal and replacement a pain. This also seems to be the case for other Key line toys, so this is something to be aware of.

NOTE: Cal Exotics (who head Jopen, at least in the US) has noted the issue with the battery compartment. The upcoming toys from the Key line that have narrow battery cages will be altered so that this won't be such as issue. It might be best to wait for this change to occur if you think this will really bother you as a user. There is no word of what will be done to the first wave of Ceres and similar toys that came out.

2. One Intensity: I understand if patterns are only one intensity. I consider it a bonus if I can alternate the strength of a pattern. However, if offering modes, I expect a low and hi standard vibration. Ceres only has one intensity, which can be too high for some users. It's also not Hitachi wand strength, so it only can really please a band of users who fall below clit o' steel and above sensitive.

3. Value Factor: There are better toys for less. The redeeming factors of Ceres are that the silicone is a great quality, and it comes in blue. Other than that, you'll find better toys for less. Unless you nab this on a great sale, this could be quite a toss up.

    Nice review! I dont understand the key's choice to just have one intensity either. It does limit who will enjoy this toy. Thanks for the review!

    Thanks for the great review & the comparison! This is difficult for me to choose because of the single power setting. I'm surprised Jopen didn't do a better job considering the pricetag.
