Suction on straw was terrible and never worked

I read the reviews that talked about adjusting the seal making sure the straw spout was in the position etc but was still having problems

I was putting lemon in my water and thought the straw was up against the fruit so i took all fruit out and still suction was difficult

I put ice in it before i go to the gym and it melts pretty fast and doesnt stay cold long
