Strong construction, wheels roll smooth under a heavy load. I used to work events at a large hotel and although this isn’t industrial, it’s fine for residential use and fits 16 might lite folding chairs perfectly. Gone are the days when I ask for help from several people to move chairs from the shed to the chow area. I just roll this puppy myself and have a helper unload. One gripe is the wing screw doesn’t align to go through the holes for the arm bar attachment. To get this to fit perfectly I’ll probably need to drill the hole through the bar a little larger. For now it still works, it just needs a touch more quality control. Also, the wheels are a tad small so this will not roll well on dirt or grass. But for textured concrete patios it rolls fine.
