Honestly, the customer service is 2nd to none. My last order I placed, I paid for 2 day shipping, but when it was sent out, they sent it normal shipping. I e-mailed their customer service, and they next day shipped my exact same order, so I would have it there when my original order was supposed to be there, no questions asked. I will be an Adam's lifer specifically for their customer service. The fact their products are awesome is obviously a big factor as well, but customer service and Made in the USA are the reasons I will always use their products.
