I can vouch for
https://www.docteur-vaporisateur.com/
Just ordered from them last week and can confirm this is a proper business that ships really fast. They have a great selection of items that are usually not seen in Europe.
I have no idea why their page shows up so much lower in the search results than La central vapeur, if only I had known about them before I would have saved some headaches.
I also don't understand why people recommend La central vapeur, including some YouTube channels promoting them. In my experience they are to be avoided unless absolutely necessary.
My first two orders that were relatively eventless took them over a week and some emails to send.
Now I am stuck for two months emailing back and forth, had to call them twice, after weeks got refunded the wrong amount, all for an item that was out of stock and I was never informed. I know that they just moved warehouses but it doesn't really serve as an excuse for how chaotic the whole thing was.
