As for the quality of the plastic, it is very good. One problem it has is that the cap in front of the nozzle does not close properly. It frustrates me every time I try to screw it on. It hasn't popped off yet, but it's difficult to find the right position to start. (I should note here that I am not someone unfamiliar with mechanics who can't find the starting point). They could make it thicker (it's too thin) to make things easier because it already has an O-ring seal. Another downside is that although it has liter markings, they are in the color of concrete (orange), so you can't see the level well when filling it (you understand now... put a little more gasoline, let me shake it to see where the level is, put a little more, etc.). If this line was transparent, things would be much better (you would go to the gas station, quickly see with a glance where the level is, and that's it)
