Great Service From Patrick!
Thanks Patrick for helping us sell Kill Cliff! I am excited to try Endure!
My favorite beverage!

I seen this product advertised on …nockontv
I seen this product advertised on nockontv. My son is big into weight lifting and always wants me to buy him these drinks that he says are good for you. Well I seen that this drink didn’t have sugar in it and that was the first thing that caught my eye. No artificial sweeteners and supporting the navy seals and made from an ex navy seal was a bonus. So I bought him a case of the variety pak for Christmas.

I was at a charitable event at Kill Cliff. They were out of my size but you guys got online ordered my size right there for the same promo price! Great customer service & friendly!
Overall good
Product is good and I appreciated the deal run around Thanksgiving. Essentially, I got 4 cases for the price of 3. My only gripe was they were delivered on the steps of a public area when the mail room is one door over and deliveries are commonly left there. Not all your fault. Easily could have been lost product for both you and me.

We have had some issues with expired cases being sent to us. Some cases expire 4-7 weeks from the day of delivery, we are a new gym (only 1 year old) and normally plan to place orders that will last between 3 and 4 months normally to catch a deal or limit the frequency of ordering. Our Rep Joe Assencoa has always been awesome about rectifying the mistake, and sends replacement cases. I just wanted to say thank you for this awesome customer service. I hope he is recognized for his help and great customer service, I truly enjoy the product, brand and people over at Kill Cliff. -Marshal Szyndlar Owner Crossfit Override Thomaston CT.

My friend gave me one to try after a workout and I absolutely loved it! I drank one before my workout today and it just helped me focus without the pre workout jitters.
Great products
Great products, and incredible support for Boxes everywhere!
