Got this as a daily packer/STP. My urethra is pretty far back & unfortunately the STP function was completely impossible with my anatomy & resulted in spills no matter what angle/position I tried. This was frustrating, since this packer being an STP gives it a hollow foldable shaft & unrealistic tip, which are features I don't want in a regular packer. In order to get any use out of the Prince, I trimmed the tip to my liking & filled the shaft with a soft piece of foam so it doesn't fold while I'm packing with it. If you already know that your anatomy works with most STPs, I think the Prince is a decent choice for a low budget prosthetic, but definitely wouldn't recommend as a packer!
