This quencher is perfect! The flip top works well and so far has been 100% leak-proof. I got this because i drive / make deliveries in a tractor trailer. The swivel handle is sturdy and convenient to locate the tumbler without taking my eyes off the road (same for the flip up sipper). I can easily recommend this with full confidnce to all my fellow professional drivers!
Pro tip: I fill the cup completely with ice before adding water. Then i just add water throughout the day and it stays pretty cold for about 12 hours depending on how many times I refill.
LOVE this bottle for water. My daughter is extremely rough on her bottles whenever she takes them to school and the other one kept breaking or cracking on the top however this bottle solved that problem. It's absolutely wonderful I've watched her drop it a hundred times and it's just fine. My only complaint is I wish they made this style in all the colors
