You're right, a real demo would be better. The reviews aren't fake, though; they're from my friends who were fiddling around with my prototype, which has no hardcase yet. The response has been good so far, so I'll post an update with a demo of the product soon. Thanks for pointing that out, I'll work on it :)
Thank you! If you sign up for the waitlist on the aibutton.io landing page, I'll send you an email with answers to your questions once I've set up a product page and start selling.
I expect the product to be available in mid-August. A demo, along with information on price, battery life, etc., will be available in mid-July. I'll then email it to everyone on the waitlist.
