Review on 🥤 12 Ounce Stainless Steel Kids Water Bottle for Girls - AUTO FLIP Design, Double Wall Insulation, Leak Proof Thermos, Handle & Spout, BPA-Free Sports Bottle for Boys - Vacuum Insulated (Blue) by Tim Woods

Arrived quickly, in good condition. A simple bottle with an inner straw, a fold-out straw-like outer tube, and a tiny vent that blocks when the tube is closed. The vent is small enough not to be completely silent, but as long as the dog whistle doesn't hurt you, that's not a problem. The mouth is wide enough for a bottle brush or small ice cubes; However, don't expect to grow big. The sleeve protects your hands from hot or cold contents, but don't expect it to be insulating. I was expecting a single wall bottle, like an aluminum can, to cool its contents quickly in the fridge and it wouldn't last long enough to warm up anyway. That's what happens, and for that use it works better than a vacuum flask, although the latter would be better in larger sizes and for long trips.
