Well built.  I have rented one of these (same model) from my local garden supply store for several years.  It is a great spreader.  Packaging the item came in was poorly taped and the bow was just about to come open.  Inside the Amazon box was the manufactures box.  There was no padding inside either box so parts had jostled around a bit, some parts got scuffed up, but everything was there.  Assembly instructions were adequate but could have been better.  Tools needed to assemble include a Phillips screwdriver, 7/16 wrench and socket w/wratchet, and a pair of pliers.  Assembly time was about 45 minutes.
