Quick results, very knowledgeable staff and fantastic customer service! I had the results in 2 days and Ritch did a great job of explaining the results in an easy to understand and very calm manner, (on a Saturday too) Harvest is always a stressful time and these guys have your back! I will only use ETS from now on
