You are aware that this Kickstarter project dates back to July 2021, and by September 2022 it had been on the market for almost a year now?
They were about to be delivered, in September 2021.

I received mine a fortnight ago.
It is a product that may seem a bit expensive but it is well worth the price paid.
For less than CHF 10.00 you can buy adapters that will allow the use of CH sockets.

For delivery times I can't give you any information, but for the front sockets you have to order or ask for EU-CH adapters, because CH appliances with earthing (3rd plug) cannot be connected.
