You're welcome Douglas.Curtis! Loved your Full pH Swing post, over observation I was heading tp the same conclusion, yours made lots of things sound to me!
Yes the German one seems to be built with the classic German durability in mind, thick copper PCB, good solid solders and neatness all around, a shame this seller went nuts pricing each at 10€ now.
I'm sure tho that these could be being sold under other brand names in Europe, possibly cheaper.
Quality 13-15W SILs go for 5-6€ each on good deals nowadays.
