I busted the tamper that came with my vitamin and thought I didn't really need it because I mostly used it for green smoothies. Then I started making my own almond butter and it took FOREVER! ! So I ordered another tamper and was amazed at how fast it makes my almond butter! What used to take 30 minutes,  now takes less than 5, my smoothies take a lot less time to make wlso. I don't know how I lived with my tamper,  but I never will again !!
