Review on 64Oz Motivational Water Bottle With Time Marker, Straw & Leakproof Tritan BPA Free Jug For Daily Fitness, Gym & Outdoor Sports - Fidus Large Half Gallon by Mario Hernandez

I've had this water bottle for about two weeks now. It's been great for increasing my water intake and easy to clean. I deducted one star due to the top. As the title of my review indicates, the top is super hard to open. I don't screw it on too tight but, for whatever reason, it creates a really tight seal. Whenever I want to refill it I either have to get a coworker (I use it at work) to help me open it and/or lightly bang it on the counter top along the seal to loosen it. Today (11/18), I banged it on the counter top AND got the assistance of two people and it still won't open. I don't know if its my water bottle but wanted to give buyers a heads up. Upside: it is definitely leak proof.if you can get it open.
