In the photo it appears with two handles BUT in reality it comes with one, the one on the side of the tap, which makes it relatively difficult to use. I had it for fire safety at a campsite and there I discovered that the handle I wanted to use to empty it over the fire was missing. Luckily I wasn't alone and we managed to handle it without the extra handle. It was a real hassle!
Other than that, yes, the water capacity is large and ideal

Cheap, simple. It leaves a hair here and there but for its price that's expected. Ideal as a "disposable", e.g. for a project and then throw it away.

It suited me extremely well. I like that it gathers a lot when it's empty.
4 stars because the faucet it has is too small.
I recommend it for purchase

Flexible and convenient for storage when empty, extremely durable and waterproof when full

Initially, it is convenient that it is made of soft material and you can fill it or fold it up so it doesn't take up space. I didn't notice any problems with the material and the seams, but the plastic screw cap broke when I tightened it once. I don't remember applying much force; I just tightened it without forcing it (no more than closing a plastic bottle). I will try to glue it to get a few more uses out of it.
