We travel a lot and needed a new bottle for our dog's water. This one is all one piece to grab and let her get a drink vs our old one that you have to fold down a silicone flap and it hurts your hands to do that. All I have to do with this bottle is turn knob to let the water flow so she can drink it and when she is done, I turn it off. It has filters that come with the water bottle as well. #RankBoosterReview #Sponsored https://www.amazon.com/Dispenser-Antibacterial-Portable-Including-Cup-400ml/dp/B074CWMQFS #XUANR
