I like this so far and the herbs I planted are still growing, but I don't think the float level works at all.  I am not sure if I did something wrong, but it is too late to diagnose now that the dirt and plants have been added.  I like the concept, but it doesn't seem to work.  

The instructions on how to use the planter and add water are non-existent.  I wish the manufacturer was much clearer on best practices in using the garden and its features.
