Do you have a big blender and want a mini bullet type blender... save your money. Almost 90 % of the blenders out there have the same thread as a Mason jar. YES YOU CAN BLEND RIGHT INSIDE A MASON JAR.. smoothies that you can just drink out of the jar . No having to wash extra dishes, no having to spend extra money.
Bonus tip .. nalgene and kleen kanteen and msr wide mouth bottles share the same lids. So you can swap lids for different purposes.
