I wouldn’t recommend. Sometimes you can not even use a regular toilet for a few hours, because the toilet is clogged and pee every where. This is very bad if you’re in a bus for longer than 9 hours. I had to pee in a plastic bottle. Drivers who don’t even speak English, are rude and sometimes even racist. And don’t expect a refund when they don’t deliver things they promise. They won’t refund anything.
