It may be a bit expensive but I consider it an excellent investment. In terms of design, it is outstanding and you can feel the quality as soon as you touch it. It is the only one with a straw that truly seals (The straw is made of silicone on the part that comes out of the lid and metallic on the inside). On a scorching hot day outdoors, the ice cubes lasted for 10 hours. No leaks at all and very handy.
