shopping was pretty straight forward HOWEVER im not a sprinkler pro. The reason i went with the basic kit for the MP Rotator was because of the youtube video and i was sick of using my other water stuff. I looked at both basic and pro kit and no joke thought it was just the bluetooth piece. Once i received the basic kit i was very excited to use it to find out that it wasnt the same and i had to order the check valve and the other regulator. Honestly i was extremely annoyed because the site doesnt really explain it enough in my opinion. Thankfully there was free shipping for those otherwise id return everything. The site should have imaged of the basic vs the pro kit. p.s. your chat support isnt the greatest
