Watch out, this stuff exploded out of the bottom of the tube on me twice! Lost everything, 2 oz plus, sticky mess everywhere. tore thru 5 layers of coffee filters. It was half ground up bud and half kief, it was even mixed not seperate. Ive run BHO probably 50 times and ive never had this happen before. why would kief do this? I feel stupid and empty handed! Dont let this happen to yall!
