Query: Superior Customer Service

I bought the Pack Rack system for this year's hunt because the mounts are easy to remove when hauling other supplies to our campsite. I was very disappointed when the rubber mount broke off from the stem after only two days of moderate trail riding. I emailed the company and they were absolutely awesome. They shipped out two new mounts immediately so now I have a spare. That is great customer service. You can trust this company to support their product!
