I have been wanting to get back into anal play for some time now, and when I came across this set, I knew it was exactly what I needed. With three varying sizes, it's exactly what I wanted for training myself to love anal again. I'm not a huge fan of the material, but with this set, it's not uncomfortable at all. With a little bit of silicone (or water-based) lube, they slide right in, all nice and tight. Personally, I feel the biggest size is much too large for anal, but I would definitely use it as a standard dildo. The smaller two sizes are perfect; those are the only ones I tried. The smallest one was great for trying something other than a standard butt plug. This was a more uniform size (vs. something of a tapered shape) and felt more like an actual cock going in.
Packaging was fairly basic, and while it isn't discreet at all, it does help keep them separated and clean of dust and debris. Cleaning them was also an easy task. I simply used my Eden toy cleaner and then rinsed with water.
As I mentioned, the sizing was relatively nice. The sizing is as follows:
Smallest: 3.5" long x 1.5" diameter (3.5" circumference), Insertable length of 3"
Medium: 4.5" long x 1.25" diameter (4.75" circumference), Insertable length of 4"
Largest: 6.25" long x 1.125" diameter (5.5" circumference), Insertable length of 5.5"

As you can tell, there is a significant size difference between the middle and largest sizes. I, personally, think that it's much too large of a gap between two sizes. The largest one is way bigger than the other two making it not as useful to me.
This toy set is great for solo or couple play. The smallest size would be great for a beginner, and the largest for more experienced users.
