Allegro is a highly textured glass dildo that can be used by anyone looking for some pretty intense, yet pleasurable sensations. It can be rubbed on nipples or the clitoris for external stimulation different than the usual. Where it stands out for me is vaginal use, and some g-spot stimulation. I wouldn't recommend using this one for anal because there is no flared base to keep it from slipping too far inside, but it could be used with a partner if only inserting a small portion (as long as you can handle the texture). Allegro is a little on the long side, so fast thrusting can lead to an injured cervix.

Allegro is made from tempered glass, which is also referred to as Pyrex glass. It is a very safe toy material and ranks a 10 on Eden's safety scale. It is nonporous, phthalates free, and body safe due to the lack of harmful chemicals. It has no smell or taste and is very firm to the touch. This one is not realistic in appearance or feel. Glass holds temperatures really well, so if you want to experience some cold or warm sensations then throwing Allegro in some ice water or warm water before use can be a lot of fun.

What sets Allegro apart from the other toys in my growing glass collection is the texture. It has ridges that are engraved in the toy that cover the entire shaft. The ridges are of different sizes and are not uniform in appearance, I think this makes them even better. I would describe them as feeling a little bit like ribbed condoms, but a lot better and more intense. This texture is for those who know they enjoy texture, especially on firm toys. I don't recommend this for beginners. For me, this texture is extremely stimulating and I love it on my clitoris and the way it feels for my vaginal opening.

In addition to the texture, Allegro also offers a shaft with a couple undulating curves and two ends that shaped slightly differently. The undulations of the shaft also add to the experience. One end is a little more tapered and the other is more round. The tapered end can hit my g-spot when inserted and the texture rubbing on, and what feels like pulling at, my g-spot is wonderful. The shape is something that most people will not recognize as a dildo, and you maybe could say this one is some kind of kitchen tool without too many strange looks.

Allegro measures 7.25 inches total with about 6 insertable. It has a diameter of 4.5 inches in the middle and at the round end and a diameter of 4.25 inches at the tapered end. The areas between the bulges are a bit smaller than this. It is a pretty heavy glass toy, but I like my glass heavy because I can feel it more. I found the size of this one, both length and girth, to be ideal for reaching the spots I wanted to and for allowing my vaginal walls to hug the toy and feel the texture even more. The size of this might be a bit large for those who have never used an insertable toy and the texture will most likely deter most beginners.

I like texture, especially on glass, but I was still a bit concerned that Allegro might be a bit above my comfort level. As soon as I rubbed it along my clit and then inserted it I was in love with those ridges. These are the best feature of this toy, as they are designed to be the main focus. When I am warmed up I don't need much lube with this one, but in general I need more lube than I do with most of my other glass toys. I am able to use this one multiple days in a row and not have any issues with the texture becoming irritating.

To clean Allegro, use soap and water or toy cleaner. I find that running water works best, and sometimes a cloth might be helpful in making sure the ridges are thoroughly cleaned. Allegro can be thrown in the dishwasher (no soap) or wiped down with a 10% bleach solution to be sterilized.

At least some lubricant is needed when using Allegro, and one of the good things about glass is that it can be used with whatever type of lube you want. Silicone, water, and oil are all safe for use with glass.

Allegro can be stored in the pouch it came with, or any other toy pouch to keep it safe from damage. You don't have to worry about glass reacting badly with other materials, so even if you don't keep it in a bag it can be stored wherever is easiest for you.

Allegro comes packaged in a clam shell type plastic container. You could keep your toy in the packaging if you wanted, but it includes a purple velvet bag that works well (although it isn't very padded). There is a little bit of information on the package, but a lot of it seems to be in German. I think this package would be cute for giving as a gift as long as the person is in the right environment for receiving a sex toy.

I usually only enjoy texture on glass toys on my clit for warm up, but I found that I liked this so much that I was able to orgasm from sliding the ridges up and down on my clit. This was something new for me and I really enjoyed it.
Once inserted Allegro gives the most wonderful sensations for my entire vagina, especially my vaginal opening. My muscles wrap right around it and the texture becomes even more intense. It is like the texture suctions and pulls on me internally, in a really good way. After I am warmed up a bit I can get some g-spot stimulation and the ridges on this one do the job every time and I can orgasm pretty quickly. I love orgasming with Allegro inside of me because the contractions make my muscles grab hold of Allegro even harder than they were at first and this makes for a great orgasm.
