So, I too was one of those people who opened this and, out loud, said "Oh my gawd..."
It looks enormous. I'm pretty sure it is, but I haven't taken the time to measure it to see if it really is what the packaging says.
However, I'm not at all experienced. This is the first "toy" I've ever bought, and the only person I've been with was "average" or below (statistically I guess), and even I can handle it. It takes lots of lubrication and patience; it's impossible to try to hop on without already being completely ready to go, or it HURTS! If you can warm up to it though to use it, it's great! I've never been able to achieve as many multiple "O"s as I can with this.
I like the color, the material is just right (vaguely bumpy and uneven, but not painfully so), and the suction cup is very sturdy and fun!
The only complaint that I do have is that, while the smell isn't bad or even really noticable, the taste will stay in your mouth for hours. And yes, it's a very plasticy, strange taste.
Other than that, I really, very much recommend it!
