Rated 2 out of 5★ by eab324 Not as it should be Although this looks like a good product, after 3 tries, I give up!! It has a poor functioning straw that I removed altogether. I like to freeze drinks and then take them to work. I am a teacher and we don't have air conditioning. I like to drink what I bring as it defrosts. When I turn the bottle to drink, it always leaks. I have to wrap lots of paper toweling around it to keep my clothes from getting wet. I would like to return it!! 10/02/2008
Rated 1 out of 5★ by bcsy Bottle is not useable The inside straw does not stay attached to the top of the bottle; thus, you cannot drink from the bottle without taking off the top. 09/05/2008
Rated 3 out of 5 Not so "leakproof" The first day I used this is had leaked all over my car before I got to work. It continues to leak each time i tip it to take a drink. I really wish it was designed better. I have looked for a large size bottle that fits a cup holder for a LONG time. What a bummer! 01/27/2009
Rated 1 out of 5★ by VIVIENEB Cracked after first use i bought 2 of these a week before school started for my son. After the first day of school he came home with a wet lunch bag and backpack. There was a long crack down the side after the first use. The second one was leaking by the third day of school. Waist of money. 09/30/2013
Rated 5 out of 5★ by Nutrachick This bottle works for me!! I bought this bottle just about a week ago and I'm loving it!! I understand what other users mean when they mention having difficulty with the suction. I initially had problems drawing fluid up through the straw until I did some checking under the cap. As one reviewer mentioned above, the air hole is covered by a rubber insert that is pre-slit. I have found it easier to drink from this bottle once I manipulate the slits on the rubber insert or stick something narrow through the top of the air hole to separate the slits. The reason I believe the air hole is so tight is to maintain its leak-proof-ability. I have only positive things to say about this water bottle!! 10/22/2013
Rated 1 out of 5★ by aadeberry Bad Plastic Taste I should have read the reviews before purchasing. Very bad plastic taste after washing it 3 times. Had another Rubbermaid bottle that my dog ate so I wanted to replace it. But bad decision to move to the Premium Sip bottle. 11/05/2013
Rated 1 out of 5★ by brownbis 2x terrible I have always bought Rubbermaid bottles. ★ I bought 2 of these to replace old bottles one was great, the other one the straw didn't work. ★ Threw it out and bought again. ★ The second one tasted terrible. ★ The plastic has a terrible smell and tastes even worse. ★ Plus both leaked. ★ Out of 3 purchase 1 has been fine. 11/07/2013
