Quality Product

[This review was collected as part of a promotion.] This cap is durable and easy to use. Most caps will leak if turned upside down, but this doesn't. Great quality.

Disappointed

[This review was collected as part of a promotion.] Why cant you make a sipping top without all the plastic. This top spoils the taste of my ice tea.

Standard Mouth Flex Straw Cap

[This review was collected as part of a promotion.] Very good quality cap. Slightly disappointed in the flow of liquid through the straw compared to my previous pull-out style nozzle. You can't guzzle liquid for taking pills, etc.

s-tier cap, b-tier straws

[This review was collected as part of a promotion.] bought this because the carry strap on my old (standard) cap broke. it's been SO NICE to be able to drink water without fully unscrewing the bottle! my one issue is that the straws that come with this cap are a bit long for my bottle, so they're getting slightly bent, but they're not bending so much that they're unusable

Newer isn’t always better

[This review was collected as part of a promotion.] It’s difficult to drink out of, where the old type was much better. Quality is there, just not a Quality is there, just not a design I prefer. Any chance I can get one of the old type? Thank you enjoy your day.
