1btn crowdfunding orders are now completely fulfilled…

Last sprint for 1btn shipment has been a bit exhaustive for us; but we did it. A few days ago, all the remaining crowdfunding orders were shipped and are on their way to the backers. Additionally, we also shipped 1btns for a few pre-orders.

Overall it has been a great journey and we have learned a few new things along the way.

Some backers have already received their devices and have been using them for a while with success.

Here are a few quick reference links for 1btn users…

When you would receive your 1btn, we recommend that you charge it for about an hour before it is put to use. This is because, to follow IATA shipping safety guidelines, we need to maintain only the minimum possible charge. A fully charged 1btn should give you service for over a month, and then some.

For any feedback, requests or help you might need, feel free to write to us on 1btn@knewron.co.in and we would respond to you within 1 working day.

We would also love to hear from our backers - use cases and hacking stories you did with 1btn and more. Do write to us and allow us share it with the community.

Happy hacking!
