I bought this product because i wanted to connect my essential oil diffuser to my amazon Alexa. At first it was confusing, difficult and frustrating process to set up, the set up took me upwards of 45 minutes. Although i got there and and was relatively pleased with the functionality and end result. The plugs were able to plug in next to each other on the same set. A bad thing i found, was that that you are not able to easily connect the plugs to a routine on amazon Alexa, although this fault can be resolved through making the desired function an ifttt command.
