"I think you guys [gals ?] are the best. Free shipping on hammer products and super fast service. What's not to like?"

Proline Sports Nutrition & Equipment,

I was shopping for the product below using Google as which time I saw your Google add. This was the first I heard of your company. I went to your site and liked what I saw and proceeded to order the Optygen HP. The order was placed on late Friday afternoon and was delivered (to my surprise) on Saturday. Your service is awesome as well as your price match guarantee. There is no doubt that I will continue to use you in the future, as well as recommend you to others.

 I am very impressed with your customer service.  I was worried about getting my order with a marathon a week and a half out.  Wow, less than 24 hours and my order was sitting on the porch.  That is phenominal service.  I will definately shop with you again.  I have had free shipping take 10 days.  Proline Sports Nutrition is a site I will recommend to my many running/cycling buddies.  Thanks for the great response.  BTW, that info on the Hammer Nutrition products was wonderful!!  It helped me hone in on my nutrition/hydration plan for my marathon.  I printed off the entire 120 pages!  This is my 4th marathon.  I've trained hard, and my Hammer plan I do believe will give me a PR.
