My sister had a Generac put in about 2 years ago. It comes on every Monday morning for about 10 minutes. 2 weeks ago it didn't come on. opened the enclosure and the bottom was covered in oil. Under warranty but they are sure dragging their feet about getting it back up running.
The gun shop I worked at for years in Indiana. The owners wife shot for Team DPMS in 3 gun matches. We had their AR's in the shop even when the distributors couldn't get them.
