Aluminium is not a heavy metal and not particularly toxic. But it shouldn't be there and is not a metal needed for humans (like Iron, Magnesium, Zinc, Copper). Toxic heavy metals are Lead, Mercury, Arsenic, Cadmium. Some heavy metals are not toxic like Gold for example. There are some studies that find linkage between aluminium exposure and Alzheimer's, but other studies show no linkage.At first I shelved mine, because my wife has health issues and we're specifically trying to heavy metal detox.
I'm using mine but keeping it clean and being extra careful to minimize metal on metal friction that scratches the aluminium oxide coating when putting the heating chamber on. I'm hoping S&B do this the right way and solves this issue cleanly in the end. I don't think it's a health threat if you are careful but we shouldn't end up with a version 1 of the Volcano Hybrid that has a low resale value and is inconvenient to use. If S&B provides a clean solution without the need to RMA, then that's really great. But if not and the solution feels more like a temporary patch, then they should permit those that prefer it to RMA and get a proper fix. They will need to solve this properly for the production line models and we deserve the same quality considering that issues involving health cannot be seen as normal product upgrades we can't expect to be retrofitted.
