Product review (3 stars): Stainless steel or not
The higher the quality of stainless steel, the less likely it is to rust.  This can be tested with a magnet.  The higher the quality, the less magnetic the stainless steel will be.  A magnet test on this product revealed a very high magnetic response.  The conclusion is that if this is actually stainless steel, it is of the lowest quality and therefor has the least resistance to rust.
