I love these fellas, though as stated in the title I like the largest the most. The medium plug is alright, but it's nowhere near as filling as his older brother. And following from that the smallest is just too small. After a while since it's just barely inside the rectum it fails to reach anywhere near the prostate and the feeling becomes more of an annoyance than a pleasure. Obviously long-lasting lube is a great solution for wearing, but I've found the sensation itself to be lacking. The largest takes a bit to warm up to... but once you are. Man, it just fills you up and presses right on the special button! And it reminds you of its presence wherever you go. Highly recommend just for that plug out of the three, but if you want to switch up the sensations every now and then the other two aren't bad in that sense.
