As a consumer I say if you ordered Stainless Steel then you should get Stainless Steel.
But it sounds like another case of 'a little knowledge is a dangerous thing' for those guys doing the review.
For a start I'm not sure either of them would know the difference between Hexavalent and Trivalent Chromium.
Hexavalent chromium is highly toxic and mutagenic by inhalation,
during manufacturing.
Trivalent chromium is benign and found in trace mounts in food and fresh water. Also considered and essential element for human life.
Stainless steel used in cookware and cutlery contains about 10.5% chrome, that's the bit that makes it stainless.
When combined with steel, chromium has a valence of 0, any leaching would be Trivalent chromium.
The aluminium in a cheap dripper or drip tip is more toxic than chrome plating.
Yes, there is lead in brass but that's under a layer of chrome, if the chrome is compromised then I wouldn't use it.
Any chrome that did flake away would not combine with your juice and be inhaled, the temperatures are not high enough.
Unless you are going to grind or weld your chrome plated atty you are pretty safe.
Chrome is stable up to 1,907°C, you gonna need a big battery to melt that!!
BTW, their statement that brass drip tips are safe is not true, that's why brass musical instruments have SS, silver or gold plated mouth pieces.
