Thanks for reaching out! We hope you are loving your new adapters so far :)
The first generation adapters are absolutely still usable, and we encourage you to give them to a friend or family if they'd be interested in using our product! Please have them make sure that their car is supported, which can be checked at this page.
If they have any questions, please have them get in touch with us via our community or email into firstname.lastname@example.org.
