This is a high quality toy - the materials are great, it is heavy, and well described. I ordered this because my first choice was out of stock and the dimensions didn't seem *that* different - but boy was I wrong, it made quite the difference. Maybe I'm more of a beginner than I thought, but I found it uncomfortable.

It comes with a suction cup, helpfully, but because of its large size, it is difficult to get the leverage needed for insertion, as it points downward if stuck against anything that doesn't just have it straight up in riding position. Even with using plenty of lube, I didn't find it very pleasurable. Perhaps 6" width from top to bottom is not for me, but could be great for you!
