Weights for pop up tent with pics...and thoughts about wind.

The instructions for these weights are online so I'm not saying I'm Mr. Original here but thought maybe some pics might help others out thinking about making these. They are quite easy...I cut PVC into 3 foot sections, bought some end caps and PVC glue, added handles and eye screws and filled with sand. I've attached them to the corners of the pop up tent using bungee cords. I've had close to 20 mph winds and they have held the tent to the ground...it's swayed a bit back and forth but held.  My top tent bars are kind of at a slope so my bungee cords were sliding down them...that's why I made a hook up point using two zip ties.  I realize if a really strong gust came up they might snap but so far so good....
