I have a bladder disease: Interstitial Cystitis, therefore I need to urinate a lot, (ie on dog walks in my neighborhood, at the beach, during car rides, you name it). Squatting in public is just not an option anymore. Here are my needs: Discretion is key, comfort, usability and performance are also top priorities. I ordered "Go Girl", "Shewee", "Wiz Freedom" & “pStyle”. I tried them all right out of the box, without a “shower trial”. Initially I used my own home bathroom, standing over the toilet with my pants only as far down as discretion would allow. I also tried them with jeans, bicycle shorts and yoga pants. Here are my results: Shewee- When I used this product I had urine on my clothing. I tried using it 3 times with the same results. It’s very bulky and therefore not discrete, The clear tube must be used because the green funnel isn’t long enough to exit the urine safely away from the body. It is made of hard plastic, so it will not collapse during use but still needs 2 hands because it’s so long and narrow you need to hold both ends. It comes with it’s own caring case, which is a plus. The part of the funnel you hold next to your body is extremely narrow, the funnel itself is so narrow if one was to release a large volume, quickly, I think it would overflow. You also need to wipe afterward because if you try to wipe yourself with it, it’s just to narrow, plus now you have 2 plastic pieces that are also wet (besides yourself and your clothing). This devise is generally hard to use, indiscrete (dark green…really?) and bulky both to carry and use. I would give the Shewee a rating of 1 star. I expected more from REI. Wiz Freedom- Out of the package, first try worked fine. It’s flexible and therefore needs both hands to keep it in place and prevent crimping. This devise was not very discrete, anyone seeing you from the side would wonder about this long bright pinkish-purple thing sticking out from between your legs. It doesn’t come with a carrying case and I couldn’t figure out how on earth I would carry this discreetly in my purse or use it in an emergency. It also stays wet and there’s the issue of self-clean-up, since you are wet after use. At least it doesn’t wet your clothing so, I would give this 2 stars. Go Girl- no leaking on first try, more difficult with elastic clothing due to the flexibility of the product, good discretion, you do need to use both hands to hold it tight to your body and keep it from crimping. I liked that it folded in half- and I could fit it into a small iPhone case on my waist when not in use! I didn’t like that there was still moisture in the devise and on my body when I finished, and therefore needed to wipe myself and figure out what to do with the paper. I would give this product 3 stars. pStyle- Worked great out of the package. Just the right length, the color option of semi-clear lavender makes it discrete as well. Because this devise is made of semi-flexible smooth plastic with rounded edges you can effectively use it to wipe yourself, when you are done. By gently pressing up and away from yourself, you are virtually dry- the last few drops go out the end. If you shake it, the pStle is virtually dry. as well If you want to really get it clean, just use a little water from your water bottle to shoot down the spout. If you buy the caring case you can pop the pStyle in there quickly and easily, and carry on without any fuss. The case just looks like an eyeglasses case and is totally washable with a Velcro closure. The case also comes in a blue-jean material, it can be hung on a belt loop or on the outside of a bag, purse or backpack with it’s mini carabiner. Because it is semi-ridged it requires only 1 hand in the middle to hold it in place— it won’t collapse. It also will not overfill or back-up because it is not a funnel, it’s more of a half-pipe. This is the only one I use now. I would give the pStle 5 stars, with a BIG thank you to the people who designed and distributed this product.
