I have purchased from them before, and have had good results. The delivery was fast.
Great product and excellent customer service! I’ve gotten away from drinking red bull and energy drinks because of this.
I love this stuff! Perfect before a morning workout when you don't want to have coffee. Always arrives fast after ordering.
Ordering was simple, shipment time was short and product arrived with literature and a handwritten note (nice!). The product works, you can take your favorite non-caffeinated beverage and add some for an energy boost. The bottle is designed with a squeeze-to-measure feature that helps you to add exactly what you want (and not over-pour).
Easy to order and very easy to use. If you want the boost, but not all the extra additives you find in the over sweetened energy drinks, use Kaffn8! And try it with a lil lime.
The Kaffn8 team is quick to fil orders and the order is always correct...and of course the product is great for non-coffee drinkers!
Wonderful on time service.
Been using 8 for a long time. Great way to get that boost for the day! Just add it to whatever you drink. I put it in oj, koolaid and even water. Will be a lifetime buyer!!!!
I have been looking for a new option for my morning wake up caffeine dose, since I quit diet cola for health reasons. I don’t like coffee, tea or energy drinks. The back story for Kaffn8 was very applicable. I ordered immediately, received my order promptly and followed the instructions on how to mix Kaffn8. I like that I can easily adjust my dose as needed, and mix it in a variety of sugar free juices. This product is exactly what I wanted! Thank you
Great product, I use it daily in my protein shake. Additionally, great customer service.
Very smooth process of purchasing
Service was great, arrived quickly!
Great communication. Fast shipping.
Lightening fast shipping, well packaged; no leaks. Now I can make my own caffeinated beverages!
Good product, easy to use, work well.
Wanted to make my own Caffeinated chocolate milk and this did the trick! Super happy with the results!
This company has always filled orders promptly and in a friendly manner.
