I don't think you can really go wrong with this shape. My only slight criticism is maybe a bit of a more tapered front end. As a "beginner," I think I was a little too ambitious the first time. Go slow! And definitely invest in some good water-based lube. It is constructed really well, no worrying about losing it and probably no worries with it coming out. At least, that is my opinion thus far - a further update might be necessary...
No major negatives. Just take into consideration what you want and need when shopping around. I realize now that no matter how great it is, it probably wasn't the best toy for me to buy first, without also having a smaller one. If you are used to bigger pieces, I think this would be a great one for warming up! The purple color is also really gorgeous.
Good review!
