I had been a few other bottles, before all the where you have to pull up the shutter with the teeth. Really happy I was with this principle, especially when closing, never. For almost 1 1/2 years the Camelbak Podium is now in use. To drink it is just great, the closure is in the locked position when transporting close, just in case some pressure is exerted on the bottle. Since my daughter has also fallen off and the bottle to school and sports takes the bottle is almost daily in use and also lands therefore exactly as many times in a dishwasher. Nevertheless, she looks, apart from a few scratches times, apart from new. Even the print is clean in the dishwasher matter. This is the shutter to clean bad I can not understand. The silicone mouthpiece is taken off and put the lid in the open position in the basket. Both lid and closure are still tight as the day. Two more bottles are now appointed.
