Query: dreadfully thick

This is a terrible product for a company as well known as Enfamil to put out, it is literally not able to be mixed, I have even used my Braun handheld mixer, I feel like I am torturing the baby trying to suck this thick slime out of the bottle, I bought a case of six and what a waste, not even one can will ever be finished!! Stay away from this formula! Frustrating!!!!!!!!!!
