  • Solid build by Rob (on 10/30/2017)
    I like the strong construction on this panel. Very lightweight and durable. I would like the pictures bracket/clamp and pole assembly to be offered or at least a site that sells them referenced here in the description. It does not have the screws actually embedded as these panels claim ... But I kinda like that. Great product though!
