Luke can be used both vaginally and anally due to its flared base, and given the flat base to this toy, it is also harness compatible. The O2 Luke can be used solo play or easily on a harness for a partner. Luke is here to please. Though you should exercise caution in getting this toy, it is an average length, but it makes up in this by being a very thick toy. If you're used to very slim toys this may be a bad choice for you. Due to his thickness, I'd recommend a nice amount of warm up time and some lube, for even if you're used to sizable toys it can leave you pretty sore if you're rough with it. If you're careful and take it slightly slower then you should be pretty pleased with this toy, I know I was. This toy is made of a very safe material, it is fully silicone and it is able to be sanitized and disinfected through boiling or a 10% bleach solution. This toy can also be used with any lube, as long as the lube is NOT silicone based. Do not use silicone lube with silicone toys as it will damage the material.

The material is made entirely of silicone and has no smell or taste. The head is very smooth, and shiny looking like plastic; However the shaft has a softer more realistic feeling texture. This toy does have slight drag to it, so it can get caught on your skin, so I would recommend lube and foreplay of some sort before use. The material of this toy is made of Tantus' Dual Density silicone, so the outside is soft and the core is hard and stiff. The dual densities gives the O2 Luke a more realistic feeling, and though its core is slightly too hard to pass off as real, it still is very realistic considering how safe the material is.

This toy is focused on realism, so of course it looks very much like an actual man's sausage, so some may not appreciate this at all. I like the design of Luke very much, I appreciate that unlike other dildos it ins't covered in a ridiculous amount of veins. As well as that the O2 Luke is not overly long yet not too short, it's just the right length to fit the average user. I was mildly put off by how thick this toy is, I figured it to be a pleasantly average dildo until I realized it had a kinda large diameter. I was both excited and frightened, but with some preparation I found the O2 Luke to be rather nicely filling. For those who tend to be unable to accommodate very much girth, this is a bad choice. Though this toy is softer on the outside, the firm core does not allow too much give. I do of course think that most can probably work their way up to luke even though he is a big boy. Relaxation, lube, and arousal goes a long way. For those with roommates and family members, the O2 luke may cause some trouble. Given the size of this toy it is possible yet still slightly difficult to hide on short notice if anyone crashes your party. A pillow or a thick blanket could be your hero on such an occasion, but a sheet will look very suspicious.

I do not have a harness so I could not test this out, but the flat flared base makes it harness compatible. I used it solo vaginally and it worked nicely. Admittedly I don't fancy anal, and my boyfriend doesn't appreciate it either. However given the very flared base it should be safe for anal. Though Luke is still a thick toy so remember to use lots of lube. I personally can't find a comfortable way to do so, but it is possible to sit Luke down and ride it that way. Luke does not have a suction cup, but he stands up himself pretty well. In terms of holding this toy, I hear that some hold it by the balls. I myself find it easier to hold when I turn it upside down with the balls facing upwards, I grasp the base around the middle and bottom with my hand. I feel I can thrust it better when holding it like that as well. As for stimulation, I personally can't get by with only vaginal penetration so I use a bullet or simply use my fingers for clitoral stimulation. The texture of this toy, while nice to the touch, is a bit annoying due to how it drags, so I'd recommend using a good amount of lube.

Due to the very safe silicone you can really clean this toy rather easily, and it can be sterilized. You can use soap and warm water, or water and 10% bleach solution. You can also of course use toy wipes or toy cleaner. You can also boil it, but make sure not to boil it too long unless if you want to melt your toy. Like all silicone toys you should not use a silicone based lube on it, as silicone on silicone contact tends to lead to a bad reaction that can ruin the material of your toy. You can use water or oil based lubes if you so desire, anything but silicone based lube.

The toy comes packaged in a relatively simple clear plastic box, so if you try and give this toy as a gift you may want to wrap it as it is far from discreet. In fact, The packaging proudly displays Luke for the world to see. I personally wouldn't say the packaging is suitable for storage as it is a tad flimsy in my opinion. Unless you have no other option, you would truly do better throwing it out and finding somewhere else to store your toy.

I cannot put enough emphasis on this, but the O2 Luke is a sizable toy. The length is average but it is still a rather thick toy. Even though some may find it a breeze to insert, for others it may not be easy at all which is why I give so much warning. I would strongly recommend being careful with it, for you might hurt yourself. It's not an impossibly thick toy, but I'd still advise not to underestimate it too much. Don't forget to use lube and try not to just shove it in, do a bit of foreplay or prep or what have you.

I was rather cautious of this toy at first, considering its thickness. But with a bit of work, I was able to get used to how filling it is. I did rather enjoy this toy and it tends to be one of my go-to toys. I can't use it alone to get off, but with some other sort of aid (such as a bullet), it is quite lovely. Of course, I am used to smaller toys with less drag, so I did once get a bit over-zealous with thrusting once. I ended up rather sore in places the next day. It wasn't too bad, but it was still a tad unpleasant. I was a tad disappointed at how very firm it was, for it slightly takes away from the softness of the outside. However this toy is still quite realistic, and I adore how long-lasting the material is in comparison to more skin-like materials. If anything were to happen to this toy, I would probably get a replacement since it is one of my better toys - Though unless I were to lose it or something, I'll probably have this toy forever, the material is great!
