This is spindly and should only be used at rest or at a slow no-wake speed or else I think it will snap the articulating pieces.

the pieces fall apart

When the wind blows the connection pieces don’t lock firm enough to sustain the wind and will collapse or bend the opposite way

Little pieces that are necessary to hold the nut and bolt in place broke...leaving this whole item unusable.

The adjustable pieces have so much play in them, it will break in no time at all

so there's no great straight piece on the chair to attach it

The very flimsy piece of wire that holds the brolly open, gave way

I lost a piece off the umbrella through my own fault, I contacted the company to buy a replacement piece and they sent me one free of charge.

I jury-rigged it to get thru sports season, but it is just an unfortunate piece of junk

However, when opening the 2nd umbrella, the piece that opens the clamp fell off and into the river as we were trying to clamp it to the side of the boat

Piece was missing when I went to the beach, didn't tighten on my chair

Unbelievable, biggest piece of junk I’ve ever paid money for.

Cheap cr@p.

Shame as I actually really liked this product
