empty 510s

iv been using pckt for awhile now and have had it. the quality of the carts are straight GARBAGE!! the bottom always breaks and iv had the little ring where you screw the top off break and just stay in the cart and it wouldn’t screw back on, and customer support straight up ignored me! what other companies are yall using that aren’t as expensive as CCELLS, but wont break like pckt? TIA!!
