Review by Anonymous on 6/19

After 2 years we have tossed this bottle. Took a beating as a take to school bottle and did not hold up. My dd, 9-10 bit some of the spout off (her bad). And the enamel (?) on the bottle cracked and flaked even with hand washing. Dented too. IMHO - good for WATER ONLY. Bottle does not completely seal and other beverages will seep into and under the top cap. (Milk was not a good idea).

Review by KLH on 7/22

The bottle is fine, but I thought the straw would be stainless steel given the title "steel straw" bottle. The straw is not steel; it's plastic.

Best Water Bottle EVER...i am drinking from it right now after being outside all day and it still has ice cubes in it from this morning! It doesn't leak, it doesn't sweat and stays ice cold all day. I am going to look for a larger size for me now!

I love the bottle. It keeps my drinks so cold!

Review by miamaudlin on 3/1

Bought one for each of my children - they love it. Their teachers let them keep it on their desks in the classroom - distinctive - and no spill! The girls love that their water stays cold - and they still have ice when they refill it.

Review by April Machan on 2/19

My daughter loves her new water bottle - it doesn't spill and it keeps things cold for a long time. The weighted bottom also makes it harder to tip over - not impossible, but harder :)

Review by Dave B on 5/11

Perfect size and balanced approach to the needed plastic in the straw components against overall stainless steel bottle!

Our son is having trouble adapting a bit since the form factor is a bit different than the traditional plastic straw cups...this was closest we could find to that form factor.

Review by C W on 4/15

Really nice colors and designs and the straw makes drinking really easy. The best feature is that drinks don't get warm and ice can stay in the bottles for hours.
