Question about Remington XR1600 Men's Razor RX7 Ultimate Series

Amazon sells replacement blades. These are suitable for the predecessor model RX5 and also for the RX7.
Digitec's research does not seem to have dug very deep. Dear Digitec, if you sell such a product, you must also offer the consumables for it. Anything else is not sustainable.

Are replacement blades also available in Switzerland?
I did a lot of research, but couldn't find anything more valuable.
Is the shaving head from the RX5 also compatible with the RX7?
Does anyone have more information on this? It's been 11 months since the last article and maybe something has changed in the meantime? Thank you for your articles.

According to our research, there are unfortunately no accessories for this shaver.
