Good productp Product arrived quickly. It is easy to use. The container makes accurate measurement easy. Good quality.

Highly recommend it My husband hates coffee and is trying to get off all the sugary drinks but needs caffeine. Kaffn8 is the perfect solution! He uses water enhancers, adds Kaffn8 and its a dream come true. He loves the ability to vary the amount of Kaffn8 according to his needs. Tysm!! Also, the company was quick to ship the product and added a personal "thank you" note. Well done Kaffn8 👏

Excellent energy Item was shipped securely and promptly, I received mine after only a couple days. Katy included a nice little thank you note with my order, and I appreciate that touch. It's as described, flavorless, easy to measure. It's more expensive than some other alternatives but it's not the same as the ones that I've tried either. I've had experience with more than a few products and this is the best I've found.
