Just bought it,  not yet installed. Was very excited when receiving it,  but is very disappointed after knowing that magnet stick to it.  Since that means it's not 18/8 stainless steel,  can have rust.  No wonder the care manual keep asking consumer to keep the sink dry. How can a family keep the sink dry,  and clean it every time you use it.  
Thinking about returning it,  though it's a beautiful sink,  so worry about rusting pretty soon.  
By the way,  i check so many times,  can't find where does this sink made in.
