Pros : Solid Construction
Easy setup
Accommodate any shape with an 180 degree circle base
Easy way to swap seasons (we make snowflake, pumpkin, spring flower and sailboat interchangeable pieces with decorative hooks on top to hang them while they are not in the stand)
Easy cleanup after foul weather.
Cons : None and have used them for the past 3 years. outdoors year round
Other Thoughts : Sometimes there is a little wiggle room as the width of your art may not fit tight. when that occurs we have inserted a small cut sponge behind the tab(s) that hold the artwork.
