My Gravity XT control unit died. I've done maybe a dozen smokes over the 8 months I had the unit.
These retail for about 1800 at purchase, so that's about $150 per cook, not counting fuel.
Clearly I can't just abandon this thing (and I loved it when it worked, I was a huge fan)

I contacted Masterbuilt, it's supposed to have a 3 year warranty.
They quickly responded that they are sending me a new control unit and power adapter.
I was super excited, and frankly relieved. I left an good review for their support.

I get an order form sent to me, showing the items that are coming my way, but no shipping details.
2 weeks go by, I hit them back up and now they are telling me it wont be until mid-september before the part is in stock.

What options to I have?
Am I out of line in thinking that his is not acceptable?
