Obwslike i said it's the cheapest ECB they made light metal doesn't seal well the vent doors are warpped it belches smoke when i add chunks.
my wood whatever kind i use is always about 4 to 6 in. long and 1 in. wide i add 1 peice every 1/2 hour so it only belches for about 5 to 10 mins then it evens out to a nice little stream of puff.
i only paid 50 bucks for it and it has been serving me well, did my best butt yet today.[chest still puffy]. one of these days i'll break down and upgrade[no al not a treager]..now if i can only bang out a good brisket i'll be able to die happy
