As a health coach, great products are always on my radar!! This is by far the best flask I have ever owned. It's minimalist design allows you to clean it's entire surface including the inside of the lid with a small brush. Easy to maintain, great to hold. Not to mention that the team at made by Freskko provide great customer service.

Service and product were both excellent

I've only had this for a few months and already there's some sort of sealant on the metal part of the cap that is flaking off. Also, putting anything in this that's not unflavored water will make that taste permanent. Cleaning the bottle with soap will just make it taste like soap, putting mint tea in it will just make it taste like mint forever, etc. Would not buy one of these again and honestly wish I could just return it and forget this company even exists.
