Since my Sigg Water Bottle coating lacked inside, I looked for an alternative and ordered the Mizu Bottle. I especially like that it has no internal coating and that it is made of stainless steel. The design is also top. What I have noticed is positive compared to the Water Bottle that it is not possible at the Mizu Bottle it to tilt when close, bed. it is always tight. The reason that the opening is to drink large, which also affects the pleasant drinking experience. Furthermore, the bottle is not dented in shock as soon as my Sigg Water Bottle. The only drawback is perhaps that the lid only complete with O-ring seal can be purchased and not the O-ring alone (on the Mizu site the bottle is being courted as a totally sustainable compared to the plastic bottle, then you could have the seal also sell separately because the lid makes a super stable impression)
