The best part about this toy, and all glass toys in general, is the ability to acclimate the glass to any outside temperature. If you are taking a shower the toy is easily turned into a warm, not so little, shower buddy. Alternatively you could stick it in the freezer, fridge, or even cold water to turn it into a sub-zero paradise. If you have never tried temperature play I advise it highly, it provides such a uniqueness of depth to your masturbation and even partner sessions.
This toy is really great individually because of the graduated diameter balls that make its shaft. These are just perfect for warming up with, as the smaller side is easily inserted vaginally, or anally. And you WILL want to warm up before using the big end, or you are going to end up hurting yourself. However once you get going the big end feels amazing, it is nice and weighty, providing a lot of power behind your thrusts.
I cannot stress enough how careful you must be to not hurt yourself with the big end. I use this toy anally, as I am Male, and I can speak from experience when I tell you that you can bruise yourself internally, or even cause bleeding, if you get overzealous while using this toy.

As is the case with any glass toy that comes from a quality dealer, this toy is made of high strength, stress and shatter resistant borosilicate glass. This is the same stuff that they use for Pyrex brand cooking ware, and is designed to withstand high temperatures and sudden temperature changes. That being said, I would discourage users from heating or cooling this toy outside of the range which is safe to be inserted into your body. Freezing can cause just as much damage as burning, especially internally, so make sure to test the toy's temperature before you attempt to handle or insert it. The toy can withstand the temperature, but your body can not. If dropped, the glass will not shatter; similarly, if stressed, the glass will not shatter. If you do break the glass, it should break in one place only, creating two large lumps of glass, instead of a million deadly little shards.
The glass is extremely smooth, but I have yet to drop it no matter how vigorous I get with it. This smooth texture feels VERY nice during play, as it is easier to thrust than a rougher or more grippy texture such as a silicone toy.

I love the design of this toy and cannot get enough of it. When I want to have some solo fun, this toy is my go to. I almost feel bad for my other glass toy which got edged out after I got used to using this one. The shape of it is lovely, and the graduated diameter provides constant stimulation as you thrust. The largest end is such a delight to use, I have never been so satisfied after a solo session than I am after I get done using this toy.
This toy is definitely NOT something for beginners, even though it does have a narrow end which makes it easy to warm up to, the thick end is still hard to take even for me, and I have used this toy multiple times now. If you don't plan on inserting the thick end until you are sure you have the capacity for it, then go ahead, but do not try to force it in until you are ready to take it. That being said, the feeling of the thick end going in is just beautiful. Just be careful because the bulbous shape of this can cause bruising if you hit yourself too hard with it.

This toy is just all around orgasmic, for lack of a better word. The shape feels amazing as you thrust and provides constant stimulation unlike those smoother, constant width toys. It's sort of like using pleasure beads where you feel each ball going in individually. The thickness of the big end is just perfect for stimulating yourself inside, and can easily reach your G-spot or P-spot with little effort. The small end is also really nice when you are first starting your session, as it is easy to insert into yourself, providing a good way to warm yourself up in preparation for the big end, which I consider the main attraction of this toy.

This toy is machine washable, and comes in a box which you may use as a "display case" for your not so little friend, if you are into telling the whole world about your dildos that is. If you are more discreet about it, like I am (as I am Male I don't really want everyone and their mother knowing I use toys on myself), then you need to provide your own means of storage, as it does not come with any sort bag to hold the toy. The toy is safe to store in any location, as long as there is no danger of it falling or anything damaging the toy. A sock drawer is usually where I stuff this bad boy while I'm not using it.
All glass toys are one hundred percent compatible with all lubes. If your toy melted, chances are it wasn't really glass, or you were lubing it with acid (which wouldn't have been good for you anyway, so good thing it melted). The toy overall is very low maintenance, it can be washed with any non-caustic soap (this means any soap that you would feel comfortable putting on your own body), as long as the soap doesn't have any sort of gritty material in it, like exfoliating soaps. You can throw it in the dishwasher, or just wash it by hand. I prefer to just wash it in the shower as this is the location where I use this toy.

The toy comes in a cute, little box with a flap on the front, which you can open to review a little display window, just in case you are an exhibitionist and you like everyone who enters your house to know about all of the sex toys that you have. While I certainly would not be offended if I walked over to my neighbors and got a tour of their phallic objects, it's not something I would do in my own home. You can use the package as a storage box, but probably not a gift box unless you want the receiver's immediate family/friends/roommates to know that they just received a sex toy for their gift, which would be a funny prank, but not a nice thing to do.

I really have said it all about this toy by now. It is the one that brings me to climax every time, and hard at that. After I finish with this toy, I usually just have to lay down in the shower for a while and relax while the water washes over me, because I am spent. I have felt no greater pleasure while masturbating than playing with a toy anally, and I advise every man to give the "back door" a go if you never have.

I REALLY loved my first toy, it was also a glass dildo. I now own two glass dildos and a mini silicon vibe. Out of all of them, this toy is by far my favorite, it is pretty much the only one that gets playtime any more.
