In the main I am happy with with the build quality of their products but my Rothenburger blow torch plus rothenburger gas bottle was pants, it often blew itself out when you turned it upside down.
A glitch? Different times the search was performed?
I have tried this:

Both have 134 results. It's a strange one, I will keep an eye on it.
After the Ronson canisters ran out, I bought a Rothenburger, which was touted as the Ronson replacement at that time. No small nozzle, wouldn't idle, flaring, I think it went in the bin.
That was a good while ago, are they better now?

Many seem to use the Rothenburg these days, but the older blow-lamps had a much too wide flame. I have a couple of Rothenburgs, in my workshop - expensive yes, but good.
