These worked well once I went to U-Tube and got visual directions.  The boxed directions were useless for my rain barrels.  I had to adapt my rain barrel to this diverter.  I strongly recommend you go to U-TUBE and explore the multiple types of ways rain barrels can be connected, so you get the type of connection kit you need for your specific downspouts and rain barrels.  I have no complaints with WAYFAIR.  The rain barrel companies should be more clear about the process of connecting and the further materials that may be needed.
