Review on Convenient Simple Modern Ascent Straw Lid Top Handle - Perfect Fit for All Ascent and Hydro Flask Standard Mouth Sizes - Reliable Leak Proof and Insulated Straw Lid in Winter White by Damien Krzywicki

For me it was almost perfect. The top seals well, hasn't leaked in the weeks I've had it and I trust it's sealed now. The swivel mechanism is ingenious, very convenient as you don't have to rotate it 360 degrees (but it's fixed even with a short stroke), and the hole is a nice size. My only complaint is that there is no way to attach it to the bottle once I've removed the cap to drink. That means I have to keep it or keep it in a place where it could get lost or stain the inside. It might ruin the aesthetic a bit, but if there was even a small plastic loop at the top, I could attach it to the larger grip loop on the main body with a rubber band or something. At least 4.5 stars as is. Edit: I'm changing this to 5 stars although it's closer to 4.7 stars as I still want that little loop to attach the top to the lid body :) It's holding up really well, still not leaking. Sitting at my desk, I take the lid off and just place it on the container - this keeps my drink dust-free, but I can remove the lid without twisting it to drink.
