Dewalt.
I had an Echo gas unit for year. Then one day it wouldn’t start. Went straight to the Depot. I have 2 dozen Dewalt batteries so easy choice for me. Works great.
1 hour in and I definitely have a heat distribution problem. Right side is getting hotter than the left. I just cleaned it after the last use because I thought it was uneven from the heat door having a gap.
I switched the ribs side to side before the pic.
