I am only able to use one hand, literally for everything. Meaning my left hand and arm don't have the function that my right arm and hand does so opening a simple water bottle is hard for me. Normally, I will use my teeth to open the bottles and I know it's not good at all. But that was my only option besides, asking my husband for help or anyone else. This will now be my go to! kitchengadget kitchentools waterbottle jaropener LTKGiftGuide LTKunder50 LTKhome
