I gave the planter box only two stars because there was no verbage, only pictures, in the assembly instructions nor for properly installing the self watering system.  The frame required hard pounding with a rubber mallet to assemble the frame pieces; using a lubricant around the insert parts helped ease the tight fit.  I had to use U-Tube to understand how to properly install and use the self watering  
 process since this information was not included.  This could have been avoided if the assembly instructions and proper usage were explained and clearer (i.e., Step 1, Step 2, etc.) .  The assembly pictures instructions were also confusing because you first had to determine which system you had purchsed (there were at least 2 types  pictured, some of which looked like duplicates) and then check to see if you had all the parts.  This is a good product of a Canadian firm manufactured in China, and for the price, better instructions--in English--could improve it further.  .
