Product review (1 stars): Worked Great... for 10 months....
I spent close to $40 with shipping for this item September 2015.  This morning, the same burner started doing what this item had fixed - staying on high regardless of setting.  I guess I'll have to purchase another one; have e-mailed original seller to see if there's any type of warranty.  Who can afford to annually replace these?!  Are they all junk?  How hard can it be to manufacture a quality regulator?
