To be honest I was skeptical To be honest I was skeptical, I've tried enough products to know they generally do not do what they say. If they they do help performance, there is something that makes them unpleasant, like caffine, flushed skin, tingling etc. But, after a nine mile run for distance and the next day an 5 mile run with hills, the product did exactly what it claimed - no quit. I ran with pleasure - not missing the normal low gut feeling of not wanting to keep running. I will be using these products this year for two Spartan Trifectas.

Doesn't get any better. On time shipping and the drinks are delicious and chocked full of good stuff. Its hard to find a healthy, delicious, carbonated beverage out there. KillCliff has done just that. The recovery drinks are perfect for on the go and quick hydration/recovery. 5/5 would recommend to anyone. The blood orange was my favorite!

I stopped ordering Kill Cliff last year… I stopped ordering Kill Cliff last year because of the lack of communication with orders. I gave it a try this month, I ordered on the 18th, never heard anything back. Emailed my rep and was told they are on back order until the 27th. It’s frustrating when you’re waiting for a product to come but even more frustrating when you aren’t informed the product you want is on back order.

Re-Occuring Order and Grease on the cans. I love the product and have a small re-occuring order. I tried to alter and add product and was told I had to add a second order because the new on-line system would not allow me to change my re-occuring order? Seems odd. Secondly my add order this month came and all the cans had grease on the exterior. Each can had to be cleaned before the product could be drank.

I received a request for a survey… I received a request for a survey before I've even received shipping notification and the product. I loved the product at Tough Mudder, but am disappointed that when I went to track the status of my order it says to EMAIL them. Who does that? I hope it arrives soon.
