First of all, you will need to check Kiiroo website and order the products that you need on your side (For her - if you are a woman, For him - if you are a man).
You can also find some other devices here https://www.feelme.com/devices
Once this will be done and you will have the product, the member will also need it (the one for him or her).
Now you will need to log in your SkyPrivate account, go to Settings -> Public Profile -> Interactive devices
After this, click on "Add service"
A QR code will appear on your screen and it will need to be scanned using the Kiiroo application on your Smartphone.
