Myself (and my three children against my wishes)use and have used this cup every day for months. My one and only complaint is the lid sticking so the point of destroying the outer appearance of the silicone grip trying to remove it. It’s not a big enough issue that I don’t use the cup or would choose another brand. It has effortlessly withstood drops and many knock-overs with no damage to the cup. Cupholder friendly, yet I’m not afraid to toss in the seat when I’m in a rush— truly leakproof. I have recently ordered another as well as the new sport cup. I started using HydroJug when the first plastic ones launched. I love their products and am happy to support.
