Great for marathon training
This is exactly what I need. You get 2 bottles for the price of one! So you get great value compared to what you pay. It had a weird taste the first use, but eventually it went away. It fits into my running vest perfectly. And as someone who is training for a marathon, it has great storage capacity.

Will buy more.
FIt perfectly in ubofest vest front pocket. Function as expected, no leaks or anything. The opening is big enough to clean easily.. I'll buy more.

Good product
The product was the same as the published image. I received it before the estimated time and I am satisfied with this product. The product complies with everything specified and is of good quality.

Nice fit, faulty parts.
I purchased these for a running vest as they are shorter and squatter than most other flasks of the same volume so fit better and doesn't flop around well running. In that regard they're great, however the internal rubber o-ring on one snapped within a few uses(came out when unscrewed top). Without the o-ring it's useless for me as the pressure of the vest when wearing it will squeeze out most of the water, leaving me drenched and dehydrated. So unless I can find a replacement oring or top, it's garbage now.

The smell!!! and can't get water out
The awful smell of plastic and chemicals in this is overpowering and disgusting! The advertisement says odorless and that's a lie also getting the water out was rediculous! After cleaning I had to remove the top to get water out then took 20 min to get the awful plastic taste gone with food. What in the world is in this. I felt like I'd been poisoned. The ad says odorless but they give you instructions to clean it!!! Didn't work! Can't get the water out but it shows a girl just pouring it into her mouth!!! Misleading and wrong!!! Not happy!!!
