Glass probe - sex toy by WHK GmbH - review by Nefarius

A Clear Victory!

It looks simple, but it will blow you away. It feels different when used in different ways (speeds, locations, angle) and the bumps make it more than just a glass dildo.
Flared base, bulbous shape makes for interesting sensation, good average size.
A bit too long for anal, may be too girthy for some beginners.

extremely useful review


This beautiful dildo is made for thrusting! It's perfect for both anal and vaginal penetration; however, I personally prefer to use it for anal stimulation by myself. The bulbous design stimulates the anus very well. It is also very enjoyable to rub the length of the shaft along the clit; however, do keep in mind to never go from anal to vaginal with any toy, as you could end up with an infection (or worse!) because of rectal bacteria. I really enjoy using this one on my ass, and choosing another dildo or vibrator for more stimulation.

Another interesting aspect of glass sex toys is the fact that they can be heated or cooled before play begins. This one is great to pop in the freezer for a few moments (maybe while you're changing into something sexy or having a quick shower before getting busy). It can also be warmed to body temperature very quickly, if cold sensations aren't your thing.

My husband and I have enjoyed using it together, either during foreplay as vaginal penetration, or for quite a good double penetration sensation. It is a bit too long sometimes for use anally during double penetration, especially in the rear-entry position, and for that reason it can get in the way of my partner's thrusting. He wouldn't want to accidentally thrust his pelvis into it and cause undue pain to my ass, but when we're careful it's really great.

This is a great toy to introduce yourself or a partner to the wonders of glass toys. It's not too girthy, but it's also not too thin. An important thing to keep in mind when using glass toys is that they are indeed a whole new feeling, and much more rigid than the average dildo most novice sex toy users would have experience with. So, some care may be required when starting out to prevent undue pain. Use it gently and you should have no issues.

Material / Texture

It's made of transparent tempered glass, which is not only completely odorless and tasteless, but also doesn't hold onto odors like silicone, plastic, and rubber does.

It's really durable for a glass toy, so for those of you worried about it breaking and shattering, I've personally dropped it a few times on our vinyl-covered cement floor accidentally, and it doesn't have even the slightest scratch! You know how things can roll off the edge of the bed while you're busy with other things! Mine has endured quite the beating.

The texture of the glass is completely smooth. It may be a bit too rigid for some, however. Keep in mind that glass toys always feel bigger than they actually are!

Design / Shape / Size

I think the design lends itself well to anal stimulation. The bumps keep it from slipping out like a torpedo (don't you hate it when that happens!), and its flared base makes it safe in case the opposite would happen. However keep in mind that the length could be too much for some people.

As glass toys always feel bigger than they actually are, the feel of it may be slightly overwhelming to some beginners, but for a well experienced dildo user, it's quite nice. It should be just right for average sex toy users.

I wouldn't necessarily travel with this toy, because you never know just how jostled your luggage can get. You could wrap it up in layers of fabric and that might reduce the risk of it breaking in your luggage bag, but I'm not going to risk it personally. They toss luggage around too much! There are better travel-friendly toys available.

Because it's not shaped like a penis, it could actually be mistaken for glass art. It's very sparkly and I love how the light shines through it. If you're the type that enjoys having things like this on display, it would be a perfect addition. It's generally pretty discreet looking, because of this. Those with a dirty mind are going to think about putting any phallic-looking object at all in arousing places, but if a person isn't looking for a sex toy, chances are good they won't necessarily see it as one.

    • Partner play


This toy has performed exceptionally well, despite the number of times I've dropped it or accidentally kicked it off the bed and into a wall! I like how durable it is, considering it's made of a potentially fragile material. I've broken other glass toys, but this one remains intact.

Using it vaginally, the flare makes for a great handle, even when it gets all slippery, and using it anally, it's flared enough to keep it from slipping into your ass.

The shape produces some nice sensations while thrusting it, but I also found it bulbous enough to enable holding it in my ass while I use other toys.

It's very simple and easy to use, overall.

Care and Maintenance

Clean up is a snap because of the glass. Lather it up with hot water and some anti-bacterial soap for a full minute, and it's ready to be stored. You could also use toy cleaner, if you prefer.

When using it between multiple partners, it is wise to sterilize it between people. A dip in some boiling water for three minutes is just what it needs. Being that it is tempered, there's no risk of damage.

I strongly suggest storing it in a nice cozy bag, or maybe wrapped in some fabric. Even if it is very durable, the risk of damage is still there, and we're better safe than sorry!

The very simple packaging did not detract from the sparkling toy itself, which is fully viewable. Not so much discreet though. The packaging was easy to open. Unfortunately, the toy comes pressed into a block of Styrofoam, which means it's not recyclable, and therefore not a very environmentally friendly option. However, the packaging does prevent any damage that may occur in transit.

It doesn't come with a storage bag, and I wouldn't suggest keeping the Styrofoam around to store it in either. It would be best to purchase a bag for this one!
    • Not discreet


I've had the toy for quite some time, and even though it's not as flashy, pretty, or innovative as some of the other toys in my drawer, it remains a favourite for solo play, especially when I'm craving some light anal action.

I also really enjoy very quick thrusting of it vaginally, because of all the bumps, it's quite an interesting sensation. It almost feels like I could have a g-spot orgasm with this toy, despite the fact that it's not curved. However, my arm tires before that has ever happened.

Users be warned, when thrusting this toy at high speeds, the shape makes it sound very loud! At least when I use it, it's obvious as to what I'm doing from beyond the closed door, it makes a bit of a slurping noise as each bump goes in and out.
