Buying Kaffen8 was easy. Buying Kaffen8 was easy. I really find taking the liquid caffeine is very do able and does it's job to give me energy when I need it. The thing that I feel is lacking on the site is that they don't tell a person where they get the caffeine from, and whether it's been tested for toxins

good job ordering from their website was seamless. arrival of product was good. It arrived in padded envelope, despite the bottle is plastic, seems it leaves vulnerability for puncture. a small box would have have been preferred. Overall though, experience was good.

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 👏

Nice little note included in my… Nice little note included in my purchase, was received quickly and exactly as mentioned on website. I think it would be cool if they had a loyalty program. Obviously a lot of us will be ordering over and over. Thanks so much!!
