The metal ball end glides in smoothly and the silicone part stays flexible enough that I barely felt it once it was seated. Cleaning it after use is straightforward too, which matters a lot for something like this.

The metal ball end sits perfectly snug, and the silicone shaft bends just enough to make insertion feel effortless and secure. I've used it a few times now, and cleaning is a breeze since the materials are so smooth.
Owen★★★★☆
The silicone shaft has just the right amount of give, so insertion feels smooth rather than forced, and the metal ball adds a nice weighted sensation once it's in. Took a little patience to get the angle right at first, but it's been a solid, comfortable addition to my routine.
