Thank you for leaving a review here.
We feel so grateful that you enjoy the keyboard. As to the price difference you mentioned, please note that the version on Amazon (and we have it on webstore as well) is with Iceberg switches, which were launched in April, while the version for backers is with Gateron switches.
If you have met any problems when using the keyboard, please feel free to contact us by emailing to email@example.com and attaching your order number and a video to show the issue. Our support will be happy to help you out.
