great product, very happy with it.
The thoughtful little thank you card was nice.
It definitely does the job. Wish I had of ordered a larger amount, but for the first order, I'm very impressed. I've been trying to find a way to separate myself from the energy drinks and save money as well as staying away from the sugar. This is a great product that allows me to control what exactly is in my caffeinated drinks, and I love that. I will be ordering again soon.
I decided to try this to mix in drinks to replace the half of a Charged Lemonade I was drinking every day. After 2 months, I'm ordering more as this product is amazing! Easy to measure and add to drinks, and just a quick stir and I can't taste it at all!
Always a pleasant, easy transaction with the Kaffin8 folks! Great product for "fasters" to get a.m. caffeine!
Promptly filling my orders consistently and this shipment each bottle was bagged to contain leakage that has occurred with other shipments.
I get my product quickly and it is very effective, I love the whole experience! I like getting to choose what drinks are caffeinated, and I like that I never have to have coffee or soda!
I have replaced any and all energy drinks with Kaffn8. I just add 75 to 150 ml to a bottle of water, as I need it. The stuff's great, I would highly recommend if you're looking to cut back on sugary or fake sugar products.
Exactly what I need for my morning shakes. Great customer service! Always includes a personal message.
Great product, that gives you the perfect amount of caffeine in your favorite drink.
Fast shipping, quality product.
I like the ease of use and the peace of mind that so long as I use the built-in measurement on the jug I can't overdo my dose of caffeine my order arrived quickly with a handy instruction card.
Great product with great shipping. The package (bottle) was off putting to the people in my circle. They said it looked like a bottle of chemicals (poison) that should not be consumed. I didn't mind it, it's efficient and serves the purpose at hand.
great product, great customer service, fast delivery, exceeded all expectations! THANKS KAFFN8
First time buying Kaffin8 and ordering was seamless. Product arrived promptly in proper packaging. Next morning I put a half oz in my juice, barely a faint taste that didn’t change the juice flavor. A boost for the start of a day. I recommend giving it a try. 👍🏼
Great product with convenient measuring. My first product was damaged in the mail. They quickly sent me another.
Love this product!
