This toy is NOT FOR BEGINNERS, but I'm sure that's fairly obvious.
I saw the size of the box when it arrived, and I was shocked to say the least. Seeing this toy for the first time scared the living daylights out of me, but I was optimistic. It's difficult to understand just how large this things is until you are physically holding it in your hand. Evidently this isn't a toy that is easy to get inside.
I had used many toys with different sized bases, but this one takes the cake. The toy itself feels strong, and as soon as you start using it, you can immediately tell that it can handle lots of pressure. What makes this toy so incredible though is it's weight. Because it weighs .. roughly 4 pounds, it stays wherever you place it. No suction required. It is absolutely ideal for hands free play. The size is definitely too massive for most people, like myself, but it is difficult to be disappointed when it just keeps increasing girth.
This toy isn't about wearing it around, or seeing if you can get yourself over the largest part. It is about just having fun, for the sake of fun. The combination of size, weight and texture make this toy one of the most ideal for highly experienced users.
Remember to use lots of lube with this one, and you should probably use another toy to warm up before attempting it. I recommend an oil based lube, as it compliments The Challenge's texture.
