Review on Portable Urinals For Men ONEDONE Men'S Urinal Bottle Spill Proof Male Pee Bottle Urine Bottles 68 OZ For Hospital Home Camping Car Travel 45" Long Hose With Lid (Blue) by Yan Perng

Warning: The tube should be reasonably unwinded. In theory, as long as the top part is above the container, it should work. But you have to consider the rate of flow during a long trip. A fast rate of input can overflow when the tube cannot pass the fluid into the container fast enough.A two-part design with a tube is good because you want a small container so you can almost sit down and do your business. On the other hand, you need one big enough for a long trip.The quality is quite good. Sturdy plastic. It is surprising almost leakproof. The tube and top part don't seem to leak even if I put water in it and turn it upside down. The container is the same. Indeed, they have to make a hole on the lid so air can come out when fluid goes in. So 100% leakproof isn't necessary.
