This product is amazing! I love how small and compact the base is that you blend the ingredients with. It charges really fast & is so easy to connect and disconnect. I didn’t need instructions at all, it was all self explanatory. The cup is perfect because it has a small and a larger hole so things don’t get jammed as they’re coming out. I also love the lock and the hand strap which makes it easy to carry with no spills! This is a must for anyone who loves blended drinks!
