With this being my first packer, I have anything to compare it to, but this packer has been nothing but amazing for me! It's high quality, easy to bend the shaft down for packing, and it creates a realistic bulge for my height and build (5'4"). I've found that with tight enough underwear, you don't really need a harness because the material comfortably forms to your anatomy. I've been able to wear it all day with minimal adjustment!
Finding the right placement to use the stp function is a hassle, but it gets a lot easier with practice. The cup and bigger urethra allow for quick drainage, which makes the process a lot easier. I do recommend practicing in the shower, though, because the first couple of times are most likely going to be messy (placement doesn't feel like second nature at first).
Overall, I love this packer! I think it is an amazing first choice and gets the job done for anything you might need!
