This high-capacity portable toilet offers easy operation and solid construction. It will be useful for tent campers and small recreational vehicles that don't offer toilet facilities. I ordered this toilet to replace a much older similar toilet that's been used in my ancient travel trailer for years. This one is a serious upgrade at a price not much different from what I paid more than 20 years ago. This is a high capacity job. The clean water tank holds 3.2 gallons while the holding tank is 5.3 gal. That's a lot. Starting off with a full clean water tank adds more than 25 pounds to the total weight, and don't even think about filling the holding tank before dumping. That's 40+ pounds. One gallon of fresh water provides more than 30 good flush pumps. The circular flow is pretty powerful, which is not always the case with toilets like this. Getting a clean flush with this system is pretty easy (see video). The holding tank rotating drain outlet makes dumping the tank much cleaner than other models I've seen. That's important. Splashing the holding tank dump is unpleasant, to say the least. Please note the size of the seat is smaller than the typical home toilet (see photo). It fits children and small people quite well, but if you are large it might be a pretty uncomfortable fit. The unit is designed to handle 400 pounds of weight, but the seat size might be an issue. My one grumble with this toilet is the handle on the pump valve is slippery and difficult to operate. It works, but it's a bit of a struggle. It's also on the left side of the toilet, so righties may find it a bit awkward to use. Small gripe. Not a deal point at all. Bottom line (pun intended): this portable toilet is well built and should provide years of service. It's easy to use and easy to clean. I like it.
