This is one of the best cups i have baught it works great and is spill proff
These water bottles are made of stainless steel so they don't give your water a funny plasticky taste. If you like your water ice cold like I do, these bottles are amazing because they keep ice for 12-24 hours. On top of those benefits, they come with a lifetime warranty. I've broken 2 or 3 and will be receiving replacements as soon as I complete the claim process.
