Product review (5 stars): Great for pacefiers!
I bought this to wash pacifiers and sippey cup parts in the dishwasher, and it works perfectly for that purpose.  I have even found it useful for washing other small items as well.  I'm not sure why it's shaped the way it is, but it doesn't seem to detract from the function.  If anything, it allows it to fit into a tighter space in the dishwasher.
