German-made stuff is some of the best, whether aquarium-related or otherwise. I am an unabashed fan of Made in Deutschland when it comes to rifles, automobiles, motorcycles, tools and many other items. They're always well-manufactured, reliable, durable and very well-engineered...quite often
over-engineered.
But, as in all things, you get what you pay for...or, perhaps more accurately, you pay for what you get.
But...I've gotta draw the line at buying tropical fish in those little Grolsch bottles. Heavy breakable glass containers, as opposed to cushiony plastic bags? No thanks. Aside from the safety issue...for both the fish and the purchaser...I'm not impressed. Environmentally conscious? I dunno, maybe...but I wonder about the carbon footprint of making a glass jar and lid, and then expending large amounts of energy to clean it each time. It would take a crapload of plastic bags to exceed that energy and material expenditure...and if you break one (and you will!) it gets tougher and tougher to justify. I think the biggest advantage is to the store; they rope you in with a jar you must return for the deposit, only to spend another hour wandering around 6 gazillion gallons of fish and buying more!
How do you say "gimmick" in German?
