Cirkul 30oz Travel StrawSip Double-Wall Insulated Stainless Steel Tumbler with Handle, Checkmate (Black & White Checkerboard)

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.
