This is actually a pretty great system and is totally designed for you to move, replace or add to as needed and if you like component building and design ie. lego, the process is actually quite fun. Would highly recommend

Very easy to use, went this option over the more expansive wifi or Bluetooth. Can always plug it into a wifi plug for $20.

Originally had the bluetooth model worked on day one then couldn't connect by day 2 (same issue as other reviewers) so returned that and got the basic model, it plugs in but has no settings such as on/off, timer etc. and has to be turned off at mains power. I bought the basic transmitter but paired with the Wiz smart plug from Bunnings also. $27 extra and I now have a wifi operated light system controlled through the app. I was impressed It actually all synced up. Runs smoother then holmans own igardener app. and seems more reliable than using the Bluetooth or wifi Holman transmitter and only a fraction of the price. Do it this way rather than paying more for the wifi or Bluetooth transmitter. Also note you'll probably need the extra length (5m) extension cord from ... MoreOriginally had the bluetooth model worked on day one then couldn't connect by day 2 (same issue as other reviewers) so returned that and got the basic model, it plugs in but has no settings such as on/off, timer etc. and has to be turned off at mains power.
