The clip is fine works in many angels but the main issue is what you can put in it. i tried my coffee cup thermis and that didnt fit. than i tried my 16 oz water bottle that didnt fit so i tried a basic waterbottle poland spring and that fit sort of. the base is small so anything that tapers will just splip upwards. ill prob use this for a small waterbottle on a bike ride than giving this to my mother inlaw for her walker.
