They do the job. Good Idea.Cheap to buy, handy to pack, somewhat tricky to use while sitting.I like to keep such things as this in my vehicle or travel bag because you never know and you don't want to be noticed while parked or stuck in traffic. The only thing keeping it from spilling is the zipper. Getting the zipper open and situating the bag is a trick. I mean, if you could just stand up and swing it, you wouldn't need a bag. This is for being discrete and sanitary.That said, I did use one on a bus (at night) because the bus toilet was so messy.This is the second variety I have used and it does work.I recently purchased these bags for a long road trip/back country camping trip for our family of 6 (all female except dad). All but one of us used these bags during the course of our trip. They are very thick and have good zippers and hold quite a bit. We had no leakage issues. They do not gel as well as I had hoped when the bag is on the fuller side. The opening is somewhat small, certainly easier for males and young children. For an adult female it is a bit more of a challenge, but definitely doable in an "emergency" situation. I would purchase these again.Not easy to use at all.I would.say it works for males but not females :(Great for travel and easy to use. I purchased for my BBL in case I had to use the bathroom and was in too much pain to walk to the bathroom and it was very convenient and easy to use without making a mess all over the place and no post got on my hands.I’m glad I purchased this. I’m a technician that is always on the road, so these are a life saver. They’re easy to use and durable. I already purchased 2 more!We had a road trip for 14 hours and due to Covid, I was trying to avoid taking my girls in the restrooms as much as I could. It was great in that I didn’t have to take them in, they used the bag, It did the job and there was no mess.
