Gemini probe - double penetration vibrator by Nasstoys - review by geliebt

Packaging- This came to me in a plastic clamshell case. It was fairly flat and would be easy enough to store the toy in if you wanted. There was an insert with basic information about the toy, including sales pitches common to inexpensive sex toys, and information on how to use it. There was nothing notable about the packaging, but it was easy to open and kept the toy safe during transit.

Material- This toy is made of a soft and squishy jelly. It has a bit of drag on the skin, so you don’t want to use this without lube (especially if you use it for double penetration!) There was definitely a jelly smell to this. The smell was not overpowering or abnormal, but it was there. After a few washes and some time airing out, the smell has all but disappeared. The feel of the material is pretty pleasant, but it’s a bit softer than I like for toys designed to be used anally. It does feel good once inserted, but getting it inserted anally can be tough. I feel like it’s more work than I’d like to get it in, since it really doesn’t have much solidity for the first half an inch or so. Being jelly, it is very porous, so be cautious when using this and clean it thoroughly with mild soap and warm water, or your favorite cleaner. Remember that this material can not be sterilized and won’t stand up to bleaching or boiling. In addition, I recommend putting a condom over the anal probe to keep bacteria low, and definitely use a condom over this if you plan on sharing it! This toy can be used with your favorite water or silicone based lube; take your pick!

Storage- This thing, like many toys, attracts lint and all manner of other junk that might be around. I recommend keeping it stored separately from other toys and protected from the elements. I keep it in a cloth drawstring bag, but you could keep it in a Ziploc baggie or something similar. The original packaging could work as well, though it would take up more space than is ideal. Be sure not to store it next to other jelly toys, as they could potentially react together and melt or get otherwise icky and we don’t want that!

Function/Controls- The Gemini Probe is very easy to use. You twist off the bottom cap on the handle, and then insert the 3 AAA batteries. I had no problem getting the batteries in the right way with the clear diagram printed along the battery compartment, but it’s really tough to twist the cap back on after getting the batteries in. I always have a tough time closing that cap, and it drives me nuts! It just fits too snugly to go on well. Really annoying! But I always manage to shove it on anyway. Once the cap is on, you just turn the very bottom of the cap to control the strength of the vibrations, same as many other basic vibrators.

Vibrations- I’m not all that happy with the vibration strength. While this is quiet and would not be heard through a closed door and over some white noise like a TV or fan, it’s pretty weak. Even on the highest setting, it doesn’t really do too much. There is just one motor in the base of the toy, so you have to hope that the vibrations will somehow travel up through both probes. Unfortunately, that doesn’t really happen here. You CAN feel the vibrations in the tip of each probe if you touch it with your finger, but when inserted I found the vibrations to be noticeable, but nothing to write home about. I don’t think these vibrations will satisfy any but the most sensitive of users, unfortunately.

Design- The Gemini Probe is designed to be a double penetration vibrator, and it works pretty well as one. Inside the jelly sleeve, it has an inner skeleton made of many interlocking plastic joints. These joints will pop when you move them and will do a fairly good job of staying in place when moved to a certain position. This skeleton works really well and makes it easy to make the Gemini fit your body. It definitely worked perfectly for me! Aside from the skeleton, we have the specific design of each probe. The insertable length of the vaginal probe is about 4.5”, while the anal probe is closer to 6”. The vaginal probe is slimmer around the base, measuring just slightly over 3” around at the base, and increasing slightly in girth to 3.5” towards the tip. (continued)

The anal probe measures slightly over 3” at the base, 3” right in the middle at the 4th bulge from the top, and 3” again at the second bulge from the top. Since the design of the anal probe involves bulges and is irregularly shaped, it’s tough to measure it accurately, but I think these measurements describe it well.
I find the girth of both probes to be unsatisfying. The anal probe is okay, but the vaginal probe is way too small for me to really enjoy it. I thought it would be a little bigger, even from looking at the 1:1 picture, but it just didn’t register how slim this toy was! This makes it very unintimidating for a beginner or someone who prefers smaller toys, but for someone who likes more girth, it just isn’t right.
The base/handle is bright pink and made of hard, shiny plastic. It’s 4” long and has some curves and bulges in it. I find it to be easy to hold on to, but since it’s smooth this could become tough to grip if your hands are lubey! Likewise, it could be tough to turn the control dial if your hands are slippery, as there are no ridges on it.

Experience- As soon as I got this toy, I was a bit disappointed by the size. As mentioned earlier, it was just too small to look appealing to me once I had seen it in person. But, I took it out of the package I washed it first of course, dried it off, and tried it out. I was annoyed with how tough it was to get the cap on with the batteries in, but I managed it anyway. I turned on the vibrations and was not impressed. The sound was definitely quiet, but the vibrations went right along with the low sound. I knew these wouldn’t be easy to feel when inserted, but I lubed it up with some Pink Water and gave it a try!
Inserting the vaginal probe was very easy. Since it’s so slim, it went right in without troubles. I don’t do too well with longer toys, and even this with its short length was just a little uncomfortable, but this is a very common problem that I have with toys. The anal probe was much harder to insert. Because the first small bulge is all squishy jelly and no plastic skeleton, it takes a little pushing to get it in, even though it’s so small. But once inserted, it did feel nice. The vaginal probe was really leaving me unsatisfied, and the vibrations weren’t doing much of anything for me, but it wasn’t a bad experience. I added in some clitoral stimulation and had a great orgasm despite all the problems with it.
I would love to see a toy with a similar setup to this but with much larger probes, much stronger vibrations, and preferably in a better material!

I've officially retired this toy. There are enough flaws that it's just not even worth bothering with at this point. I have better toys. I do still wish someone would make a similar toy and improve upon this design, because there really is a glimmer of brilliance here!
