The battery was powerful enough to blend things well but needs to be charged more often than I expected. The tumbler, with the flip top blade is a great idea for on the go people like myself but it is bulky, top heavy, and didn’t fit in any of my vehicles cup holders. The cup itself is decent,  the straw is great and came with the interior cleaner too. Overall better than my stationary nutribullet because of my busy schedule, as long as the battery is charged. Less mess and more freedom is always a plus.
