I find this listing:
BBQ GURU DIGIQ TEMPERATURE CONTROL FOR BIG GREEN EGG NEW IN BOX 10CFM FREE SHIP
Price US$279 free shipping.
on eBay http://www.ebay.com/itm/BBQ-GURU-DIG...item231f304941
It sells 20 to 30 pieces per month
My WOLF package US$158 including shipping.
But sales of WOLF is much poorer than Guru DIGIQ
I must do something wrong.
Comments and suggestions are welcomed.
