Many products sold by "Brückner Produktdesign" aka "Heavy Metal Keyboards" are part of so called "group buys". These items have not yet been manufactured and are instead pre-sold to then be submitted to the manufacturer for production. Once finished, the products are received by us and finally shipped to you.

The dates given include a buffer to account for delays in production so items may ship ahead of time when received early. Unexpected delays can happen, so it may take longer to ship.

The primary reasons for hosting group buys are that these products are made on demand in small quantities as well as giving customers the option to buy them at a lower price compared to a single piece production.

Group buy items are designed with a specific audience in mind. They are made on demand and in small quantities. Only pre-orders make it possible for the production run to happen at all.

Group buy items are considered custom art/design items. Due to their limited and custom nature they are not refundable. Only in case of manufacturing defects an exception may be made.

Geekhack is a forum that is considered the cradle of the keyboard community. You can find more information about groups buys and keyboards in general there.

It is recommended for the buyers to be informed about the development process detailed on Geekhack. A discord server for Heavy Metal Keyboards group buys is available.
