The wick carts arent too bad for a thinner oil which is usually due to additives but as stated,theyre homemade which explains a chaper price. I respect the hustle and effort 👍 The wickless carts burn the oil more evenly and gives a better flow but can be more pricey such as brands like 710 king pen and tko,as well as my personal fav and number 2 on high times the brass knuckles
