Good box with workmanship at water level indicator

Good:
* Irrigation system works very well
* Available with or without overflow protection when too much irrigation water. Caution: If you want to open the overflow, you have to drill at the points provided yet.

Bad:
* I ordered 5 cases, 3 of which went in spite of careful treatment of the water level indicator within a week break. Reason: The float of the indicator is a plastic hollow sphere that was leaking very fast and fully running. The processing of the float acts a total of inferior, as opposed to the box itself. Other reviewers also reported that already. That is why the deduction at the stars.
* In cases> 50cm width, the box bulges in the middle, if you filled it completely with soil. I push the on something small material thickness and high elasticity of the plastic.
