If you like all natural peanut butter or any type of nut butter, this is for you. Trying to mix nut butters with their oils gives you a headache! I've tried doing it manually which takes forever. I tried this with a hand blender which nearly burned out the motor. I've tried just pouring the contents of the jar into a blender, but that just makes a mess and wastes a lot of peanut butter. Then I got this thing. It easily fits in a jar of peanut butter. It connects quickly and easily to my cordless drill, which has more than enough power to blend without overheating. It's easy to scratch into a glass, leaving a minimum of waste. It goes straight into the dishwasher with other dishes and comes out sparkling clean. Highly recommended.
