Product review (1 stars): Avoid.  Dig deeper!!
Do not buy!  Very poor quality product.  Purchased and installed in late August and dead in the water in early November.  Cheap, broken coils after average usage.  Stay away.  They will not refund or replace once the item has been installed.  There look to be better, OEM parts available from other sellers on this very site.  I should have dug deeper.
