The Bob is a perfectly serviceable product, slim, smooth, attractive with a nice silicone. But once it is inserted it doesn't do much to create a sense of fullness or hit much internally. While the Bob may seem like a great entry toy for someone just starting to explore anal play the price point of the Lelo makes it a steep investment when there are so many good products available for less. The size of the ring at the end of the toy is also a tad small.
This is a sexy little butt toy. The silicone is firm but extremely smooth. You can tell it's high quality. The shape and firmness makes it very easy to insert (with lube of course) and the ring on the end is perfect for easily moving it in and out as you please. It's not great as a leave-it-in kinda plug, though if you do use it hands free you can flex your muscles and it will move around a bit on it's own, which of course, is delightful.
