I like that the length is a bit longer than the extra small mr. limpy, but that it isn't so large that it's a huge bulge in your pants. I also quite liked how the back of this is rounded, so it feels a little more natural against you.
I didn't care for how much it got squished, but it is under 20$, so rebuying it when it gets too far out of shape isn't a huge deal, I suppose. I'm not sure how to prevent it, either.
I also found that it got little tears in the back, which is why I'm buying another one. I was very concerned about keeping it clean! (how do you clean inside little tears???) I'm not sure why this one tore like that, my Mr. Limpy never did. I might have stored it a little less kindly, so I'm going to be very nice to my replacement and see how that goes.
