My family just loves these Twinkly lights.   What is really neat is that you can add to this initial starter kit with a Twinkly line extension kit.  Depending on where you want to place these lights, all you have to do is clean the surface and remove the double adhesive liner.  Then you connect the Twinkly line to the controller and plug it in.  You can go to App Store or Google play Store to download the Twinkly app.  WiFi connection is required for operation with the app.  You can map the layout you would like with the app like synchronizing with music or creating new effects.  And if you have any questions, you can get in touch with Twinkly on their website.  These lights are bright and very very fun! We will definitely be adding to this initial starter kit.
