Cirkul 30oz Travel StrawSip Double-Wall Insulated Stainless Steel Tumbler with Handle, Azure Shimmer (Light Teal Sparkle)

After using the standard stainless steel white cirkul bottle in which you have to tilt it to drink it, i was hoping for a great upgrade purchasing this Tumbler that has a Straw feature! So, as like trying to draw liquid through a straw, plenty of sucking through to get the water to come up the straw. I was thinking the structure of the straw would have enabled an easier draw but that is not the case. Also, the fill line for the water is a good inch down from the top of the tumbler so to allow for the cartridge and straw which then makes it about 4 ounces less in water . The handle is nice and sturdy and the pale azure bluish color does have a nice sheer pastel rainbow hue to it when the light hits it, very nice. I also bought the cirkul sqeeze bottle, which is great for the athlete and I did like

I bought 3 of these tumblers. Purple, Pink and the Mint color. Pink arrived and the straw didn't work. I got these tumblers so my water would stay colder longer since I already have the original bottles. These in fact do keep the water cold longer but the flavor runs out so much quicker. With the original bottle I can have my flavor dial at a 4 and taste a difference with these tumblers I have to have the flavor dial at a 9. And even at that sometimes I have to turn the bottle upside down to taste the flavor. Great concept just need a better way for the flavor to last with a low dial.
