Conclusion
I feel overall this product is of good use. I do feel its hard to judge your correct sizing to purchase this. I also feel like it is easy to slip out vs other materials. I however feel like it also is less harsh on genitals than metal and feels less intimiating to those starting out with using these type of products. A lot of people fear being trapped with that on so it sort of slightly lessens the idea by having a less threatening look. I feel like the plastic also would be easier to escape in a worse case scenerio where someone lost the key.
