Great hunt! Here is my value for Kor Nava:

Pros:

• Iconic design. So simple but unique.
• The filter is made of coconut shell. Smart!
• The service, such as for ordering, replacing, and subscribing could be done by online.
• Ergonomic Spout and Easy-Flow. I can't wait to drink water from this bottle.
• Easy to clean. This is so important. I oftenly got some unique bottles but they're so hard to be cleaned.
• Easy to fill.
• It has No-worry Cap. We just need to press the button up and the cap is just there.
• Healthy-safe materials. It wouldn't be an eco-friendly stuff if the materials are harmful.
• It's not pricey.

Cons:

• None.
