Perfect for what I needed!. Sherry. Cordele, GA. Tue Apr 21 2026

Came very nicely packed and the build quality is very good. I did not want a plastic outer body because had an old one break apart, and this is quite sturdy. Setting it up was a breeze and the instructions come in quite handy. Until now its quite weather durable and with the strong shell I don’t think it will have issues. Overall a good purchase !. Sg.
