I bought an adapter for 35mm PRX that fits 20mm straps.
The design and quality of the adapter are excellent.
It is worth the price and the waiting time.
From order to shipment, it was 12 days and then approximately one week in the mail to get from Switzerland to Denmark, pass customs and final delivery.
Before I could get Customs Invoice and pay it, I had to use tracing in browser and mobile phone app from local mail services (carrier) "PostNord" and scan QR-code from tracing with the app. But I guess it was a rare mistake from PostNord to not automatically create the consignment themselves in the app, because they did that the last time I bought something from outside EU, and I I imagine it is usual procedure.
I do recommend the adapter.
