I have several O2 dildos, ranging from thick and long to short and thin, but I think Adam and his cousin Mikey are right in the middle of the road. The thing about Adam is that, even though there isn't really anything special to him, aside from his length and curve, I really like him. He's sort of like the no-fuss option between the other dildos in my collection (and it is a big collection).

Adam is made of Tantus's (legendarily awesome) O2 dual density silicone. He (I don't really know why I keep calling it a "he" but I do) has a nice, squishy outer layer and a firm, solid core and base. He doesn't have too much texture, but there is a definite velvety finish to his shaft. Overall, he feels great.

Adam is a fairly long (6 1/2" insertable), medium-thickness (1 5/8" diameter) toy with a very nice curve. The design of the shaft is simple, without any sort of pronounced head or ridges for G-spot stimulation, but in my opinion it doesn't need them. It's a semi-realistic toy in the style of most of Tantus's skin-tone O2 dildos (although I do wonder what happened to Mocha), so it has a pronounced head and frenulum, but the design of the shaft is more subtle and uniform. It's a nice middle ground between realistic and abstract.

I waffled over purchasing Adam for ages and ages, because I was pretty sure I'd think he was sort of boring, but I was pleasantly surprised. What Adam lacks in serious texture, girth, or length, he makes up for with that delightful curve. A curve like his makes him hit my g-spot with way more precision than I initially bargained for, and when that's combined with his easily manageable length and girth, I find myself reaching for him first on nights when I don't want to fuss with thicker or harder to clean toys. He's sort of the toy that came out of left field and gave me a very pleasant surprise.

To clean Adam, use soap and water or toy cleaner, and I would take special care around the ridge between the head and the shaft, because dirt tends to get caught there. You can sterilize him by boiling him or wiping him down with a 10% bleach solution. He's a bit of a lint magnet, so I keep him in plastic like the rest of my silicone toys. Also, you shouldn't use silicone lubricant with him, because it can damage his surface.
