like others have said ,the wood is just okay ,everything should be glued,i use tightbond II ,joints were ok,i also screw 2 inch zinc drywall deck screws,and clamps, some edges may need slight planing to eliminate gaps,but price is good,i will prime w kilz primer ,i usually dont use nails ,so screws or 7/16 medium crown staples are what i use and quickly put together w glue ,and let dry,i did have to repair a few splinters,or chips ,but have just got used to doing that so they will hold up for years,.happy beekeeping ,i found the longer squeeze clamps a must so i have 4 and holds the joints tight as the glue drys.
