My overall experience with… My overall experience with KillCliff.com was mediocre. It was nothing out of the ordinary compared to other sites, and there was nothing extraordinary about the service. The website is average, so navigating it was simple. There was your standard range of products, however, I wouldn't say they had particularly unique or specialised items. It was just avarage. The customer service was okay, but nothing remarkable, and in the end i received all the necesary informtion. An ok experience, but not one I'd be rushing to recommend, unless someone was specifically looking for something avarage.

Tastes great - highly recommend! Tastes great - I love the Berry Punch & it does give me the extra endurance for my workouts, I’ve tried a variety of brands, found this brand through Tough Mudder. No jitteriness. Also being a Navy mom - I’m a huge fan of the concept it was created by a Navy Seal.

Love it I work 12-14 hours shifts. I found this to be great as a mid shift pick-me-up as well as a great recovery drink after a long workout. Taste is similar to a flavored, sparkling water. I didn’t have any bad side effects, no heart palpitations or crash. One thing I will say is I wouldn’t recommend drinking it after a late workout or 5 hours before bedtime. I might just be more sensitive than others though. Great product!

Your website is so slow Your website is so slow, it took me nearly a full workday to order a shirt. I'm sure the shirt will be 5 stars, but it's worth a few more dollars a month to upgrade the server so customers can make orders in a timely manner.

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.
