I bought this in July, 2019 in conjunction with a KAB-250 2x50w amplifier to power 6 outdoor yard speakers (through impedance matching volume controls). Build quality is great. Once I figured-out which connectors went where (see included diagrams), installation went smoothly and everything worked perfectly from first power-up. No surprises.The power supply, amp and this panel were all mounted inside a weather proof case with gasketed door, so they're protected from the California sun and occasional rain. After 4 years of almost weekly use, this panel has held up and continues to work perfectly. I could not ask for more, particularly for the price.
