Heck, I'd buy it and use it without a second thought. The aluminum thing has never gotten any traction scientifically despite having been around nearly a century; it's just one of those urban myths that won't go away.

Of course, HYOH.

FWIW, a stainless equivalent will weight 2-3X as much, but it also won't scorch your lips like aluminum. Myself, I've converted completely to titanium, but there's nothing available for three or four bucks.

Cheers,
