IKEA buttons work well too, though.layer8 1y agoIn Europe they are more expensive than the IKEA ones for some reason, but thanks for the tip, they look nice.stavros 1y agoIt depends where you get them from, I get mine from Ali for around $7? Locally they cost around 7 € as well, IIRC.layer8 1y agoI only see prices above 9 € on AliExpress, but it's still a good price.stavros 1y agoHm yeah, it looks like they stopped making the SNZB-01, now they only have the SNZB-01P, it seems. I don't know what the differences are, I'm afraid.
