As a trans-man who gets pretty bad dysphoria, I needed a cheap and fitting packer. The Mr. Limpy extra small is 3.5 inches, which seems pretty small, but in your pants it's just right. It's about the average length of a non-erect penis. The color is a bit too pink at first, but with time (I've had mine for about 6 months or more) the color fades with use. Mr. Limpy extra small works very well as a packer because it gives just enough bulge and is a nice weight. It tends to get a little sticky, so it needs to be cleaned often, as it picks up fuzz from pants/boxers/etc.

When cleaning it, I just use regular hand soap (not anti-bacterial) and slightly warm water, and it works just fine. After it's cleaned and dried, I pat a little cornstarch on it which helps with the stickiness.

It's a really nice little packer, or gag gift. I mean, what's not to love about a tiny cute pink little penis?
The only downsides are the color, that it can't (or shouldn't) be used for penetration, and is a bit too small to make a good STP device.

Mr. Limpy XS is excellent for soft packing and it's very comfortable. It is very squishy though, and due to the material it's made of (I forget the material) it kind of warms against your body heat and becomes even more squishy. Its balls are a nice size, and it looks realistic other than the color. It also has a nice weight to it, but it is on the kind of heavy side so I honestly wouldn't let it just sit in my boxers, I would recommend some sort of small harness.

I've heard some people say it's torn, or hasn't lasted very long. I think I've had mine since around Thanksgiving and it's perfect and intact, and I use it almost every day

I would say that if using this as a packer, it's probably best to make a harness (or you can buy one) just so that it doesn't move around so much. I would recommend wearing it around your home first to get used to the weight and position. I didn't have a harness when I first started using it, and it moved and became very awkward.
