I was worried on the quality of the poly siding from initially opening it but once put together it is sturdy and beautiful. Making some sort of a level foundation is more work than actually assembling the unit. Assembly took my husband two half days by himself, be careful of sharp edges. Also be aware of the height dimensions, I thought I would have more head room/height for tall plants but it’s pretty tight in there. I was worried about the heat in SoCal but I’ve just left the front door and vent open on really hot days. All my veggies and fruit are doing great and most importantly the critters aren’t getting to them like they would have in an open garden!
