I can't rate this badly or highly. My problem now is the big lid. Opening it isn't as easy as it seems, because if you open it manually you'll be limited in your movements. However, there is a smaller opening on the back. This is smaller than the 500ml cap size (think water bottle) and is NOT pour friendly in terms of how the liquid comes out and pours into the container. You need 2 people to water properly. I'll report back if I find a solution. I recommend taking 4l. the next best thing and easier to open and pour. Update: I had to buy a 12" vise. Just be careful not to over tighten it. It opened up :) So I have no problem buying those 20 liter containers. Now my current problem is just to find some kind of pump to succeed I will be upgrading Star to 4 from my previous 3 now
