Overall, this a great idea, ships easily, assembles easily, looks really nice. Couple things though, kind of common sense...but. In the case of the 2.5'x 9.5' config, there needs to be additional cross bracing at the mid point and attention must 
be paid to orientation of branches and other fill in the 
base layer. Like I said, common sense. Also, if placing on a previously tilled plot, site prep is critical; 
make sure the soil is HARD PACKED, as our unit has developed a slight list in settling.
Otherwise, this product is a 5-star.
