My shipment arrived on time, as predicted. Very, very good performance by EcoDirect. What more could you ask for from an online material supplier? Looks like the quantity from Quick Mount is spot on & the rails were bundled safely. EcoDirect will be my recommended source to my friends & neighbors for solar.
