I'm not loving this new Sigg. I've had metal ones for years and enjoyed them, but the quality of this one is not what I was expecting. The mouthpiece doesn't have a good seal, so air leaks in when you sip leading to a machine-gun-style drinking experience. If you adjust the seal you might be able to get a steady stream for a few seconds, but then it inevitably reverts back to its air-water-air ways. Also, it looks kind of funny. It's much taller and thinner in real life than it looks the picture--it's 11 inches tall and less than 3 inches in diameter. The purple color is nice, but the lid is white, not light grey as the picture suggests. I'm returning it.Started leaking almost immediately, water forces itself out of the top in room temperature and the bite valve permanently bulges open. The dust cap made the mouthpiece smell really weird until it got lost because it isn't attached. Really miss being able to clip it onto my backpack or belt loops. The body has survived rolling around in my car and I like the red color.Not for:-active use-daily use-not for kids-not good product for your moneyBe aware : easy breakablePointless. Bought 2 and both leak. Pointless, not up to sign quality.Love my Sigg bottlesThe Sigg spout with straw is EXTREMELY difficult to draw from. I had a great deal of difficulty getting water out of this bottle. Keep in mind the bottle must be up to use it, or else the straw will not be in the water if it is upside down. And you have to really squeeze the spout hard and suck hard, and then you will only get a small trickle of water. I love my Sigg bottles, just not this design.Love the bottle overall, though the spout doesn't let you get too much water out at once which can be a bit exhausting when trying to drink water during a spin classExcellent product - I take it with me for my spinning classes and have another one for driving. The straw mechanism works brilliant in both cases.Happy with this purchase as long as the seal lasts longer than on the other one I bought.Disappointed, leaked after 2 weeks of receiving it.Split in Half after dropping it from hand height in the gym, rubbish
